Many people complain about the short battery life of the HD2. Many complain about the bulkyness and uglyness of the extended batteries on offer. Many dream that a larger than stock capacity battery of the same size as stock will become a reality.
I am interested to know what is important for HD2 users, you cant have slimness with larger battery capacity, this is a law of physics. So tell me, if a solution came about that would significantly increase the battery capacity (beyond 2400mah), look good (not a lump on the back of the phone), provide a flat surface on the back of the phone, allow you to use your spare stock size batteries without the need to swap them all the time, with the only real compromise of doubling the thickness of the phone, would you buy it for a reasonable price (less that $50)?
I guess my basic question is, whats more important, slimness or capacity (lots of capacity I mean too, 3000mah+)?
I must say that I have never complained about the battery life when using Windows Mobile, even with heavy use I could get 2 days of life from it.
BUT since I'm now on a daily basis with Android, I must say that this is a problem, I can barely get to a full day with moderate to heavy use.
Now about you question, I WOULDN'T USE IT.
I like the size and feel of my HD2 (TMOUS one) and it happens that I have two extra batteries (bought because of android) even never having to use them yet I do change them and charge outside of the phone for easiness of not having to be near a wallplug everytime.
I just put those in the back of my phone to have an ideia of the size it would be with such an adapter. I would be inpratical to have this, so deep and big. It takes the easy and sleek feel of the HD2, to a bulky Kaiser (or more) stile.
Just buy a new battery, and if needed change it ONCE a day, ONE reboot in some sporadical day is better than a ALWAYS BIG phone wich is used to the full length of battery life rarely. .
My two cents.

You get nearly a full day with moderate to heavy use? Since I put android on I barely get a full day with little use
Interesting, considering the amount of complaining about the battery life, slimness is still more important. I can see why these fake 1600mah batteries are selling like hot cakes.
Thanks for the input! Keep it coming, id love to hear everyone's 2 cents on this issue.
Extended batteries make the beautiful Hd2 look like crap.
To give an example: If you could bring a bulky backpack of energy drinks with you all throughout the day to give you more energy BUT you had to wear that bulky backpack 24-7 (even at the office at work, while your going to the bathroom, EVERYWHERE) would you?
I sure wouldn't. I don't care how much more energy I would have throughout the day...
The only people who need extended batteries are people running Android since it sucks down the battery like crazy.
battery extender a better solution.
i have a gum pro 4400mAh battery extender. it can charge the hd2 2.5x from flat and since it can deliver 1A, you can use the hd2 while it's being charged. its small size and the fact you don't need to power the phone down to top it up make it a more practical solution for me than any extended battery.
I like the slimness of the HD2 and I intend to keep it that way.
the slimness is just perfect in pocket...the hd2 is huge, but thankfully slim. if it would be both, i couldnt take it with me
and for me the extented one looks horrible..and i'm just a WM-User, so i have no batterydrainproblem
DN41
Does anyone know if it is possible to power the HD2 from the micro USB supply while I swap batteries. I don't want to have to do a soft reset which loses what you are doing. But I'm worried that without the battery to absorb the power there is a risk of damaging the circuits?
I don't want to just try it because I already blew my main board by powering the USB through a cheep adapter and a Nokia charger that supplied too much power and had I to get it repaired/replaced. I'm hoping someone already knows. :???:

Get SetCPU and Autokiller. Make profiles with setcpu, and set autokill on agressive mode. Your phone should last more than a day with little use.
I was using my original battery for normal everyday use
and the extended 2400 ah with kickstand for times when I knew I would have heavy or extended use. Next thing I knew I was just leaving the extended in all the time. It goes days on a charge and is not noticeably bulkier in my pocket and I am slim and wear jeans. Actually feels easier to hang on to. Fits the hand better and all that juice is there whenever I might need it.
i voted battery capacity :
BC if u ran outta battery then the slimness will become just overweight.
but if u have battery capacity then it worth it !
(Just a Point Of View)
I bought an extra battery off of ebay for $5.
The Hd2's battery is small enough to keep it in my wallet.
Why would anyone not keep a spare battery in their wallet/pocket and instead use a bulky battery case?
HD2 outdoor
I know, one can look crazy taking out HD2 somewhere out there in woods, but i do like wild hiking, and i do use GPS occasionally for getting directions. And My HD2 with Garmin well serves for that. For the battery - in my case i care about capacity, as my backpack and front pockets have enough space for "bulky" extension.
For "going green" - I have a wind charger (a device which charges itself when you bike using the power of wind, and can be used as a charger for mobiles), but it can charge the phone only up to 60%. So the spare battery for 3-4 days walk is a must have for my case.
My point is - It really depends on your needs. I am pretty sure extended thickness is somewhat a burden in everyday life.
Cheers
Correction: The wind charger sucks! Do not buy it. It has major flaws which render the device not worth the price.

I've been looking at the xv6800 extended battery options. Since I came from an 6700 with the monster extended battery, I'm kind of leaning towards one that is somewhere in the middle. The monster 3200 (or 33, 34... don't remember) was awesome, I don't think I need that much day to day.
I don't think the 1800 is an option, so I guess I have to choose from the ones that require a different battery door. I'm looking for the minimum increase to phone thickness.
Option 1: I can't find measurements, but this looks like the least additional thickness. 2400 Mah. I can't get a good indication on the thickness it adds.
Option 2: This is interesting due to the way it is designed, it looks like it might feel comfy in the hand... 2200 Mah
Option 3: This is pretty much the same, but squares off the back so it might lay on the desk, counter, dashboard, etc more evenly... Another 2400 mah. At that point, I might as well get the monster 3200 Mah
I'm leaning towards option 1 since it is close to double the capacity, but it looks realitively thin.
Thoughts? Opinions?
seidio makes the 3200 one but no case for it.

Yes, I was aware of that, thanks. I'm just wondering if anyone has opinions or reviews of Option 1?
option 1 adds about 1/4 inch
Option 1s picture could be deceiving since the picture makes it hard to tell how thick it is from the side. The monster battery is overkill for me. I would go with option 1 if it extends only half way out as much as the monster battery would. It would be nice if somehow I can get the option 1 battery with the option 2 battery cover.
Option 1 battery with option 2 cover.
I have the option 2 Battery with a slightly different cover...Sort of Slanted sides to a flat and the cover looks great...
But don't bother with 2200 or 2400...
Mine is 2200 and you really don't get a lot extra from it. Can't imagine an extra 200 is going to make a significant difference. You will wake up the next day with a usable unit but you won't make it through the day.
Go for the 3200 if you can get it.
That should let you skip a day on the charging if you have to...
It would be really nice to see these batteries + covers from many different angles. People willing to take some pictures and post them?
It's a battery and cover for a phone. I think if you're worried about "looks" rather than functionality, perhaps the priorities are a bit skewed.
Buy the biggest battery for your needs, the looks are going to be what they are regardless because the manufacturers decide what the thing looks like. If it's ugly, to you, return it.

I don't agree with your comment completely. Yes, looks is a comparison option, and based on that alone, I wouldn't get the 3200, but I know that I will require x minimum amount of battery, so that is not the only consideration. Some of those with the slanted covers appear that they might feel more comfortable from a grip standpoint. The 3200 might be too big as it relates to holsters, pouches, etc. I am asking for opinions across the board, not just a beauty contest
Based on Asphyx reply, I might just go ahead and get a 3x00 variant... probably the prettiest one
I have the seidio battery and extended battery hard cover, it has a rubber"y" grippy feeling to it. Looks fine and all in black. My holster fits just fine.
Not sure what beauty part of a phone has to do with it, you could have a really beautiful dead phone, but well, it's just a really beautiful brick then.
Thanks,
Has anyone found a charging base that works with a phone (6800) that has the extended battery installed? I don't want to unplug the battery to charge it and I'm trying to get away for the cable bit, I liked the base that the 6700 had.
I've done EXTENSIVE looking for this exact thing, and so far have had to mod 2 normal cradles so I can use them with a super extended battery.
The cradles because they had to be modded didn't have anything to support the device standing up, finally gave up and just use the cable on the desktop.

Here are a couple of options for you.
http://www.seidioonline.com/index.asp?PageAction=VIEWPROD&ProdID=832
http://www.seidioonline.com/index.asp?PageAction=VIEWPROD&ProdID=833
The standard dock has a 3.5mm audio port that allows you to plug into external speakers, while the Jr. version is simple sync & charge. Both will work with extended batteries.

NEITHER one of these answers the original request. The only difference between these two cradles is that one lets you keep the rubberized case on the device while charging. That is NOT the same as charging while having the extended battery IN the device using a cradle. I too would like this option. I've asked for this months ago. I have a super extended battery with a rubberized case and want a cradle that accommodates that and a spare battery to charge from the cradle as well.
To date, nothing like this exists.
Anyone bought it?
http://cgi.ebay.com/2400mAh-Extende..._Accessories&hash=item5ad84bc6c0#ht_500wt_750
I'm curious about how it will fit and if its secure.
I have this battery, and i found the fitting it not that good. I had to trim down some edges from the plastic cover to fit properly. Also the battery lifetime doesn't impress me much, so it's my backup battery now and the original will be my primal.
so is it a no buy? does it last???
man... I really wanted a long lasting battery
at last a 1 day without charge
I really use the phone a lot...
video, excel, internet, gps, games...
HD2 is a powerhouse and don't let me down (rick roll xD)
the only cons is the battery life.
=================
"lifetime doesn't impress me much"
it's really that bad? What do you think its the REAL capacity?
it's printed 2400mh...
You think it last 30% more than a original battery?
I was expecting to last 50% more at least...
I really doubt it is even 30%, i haven´t tested it thoroughly but i found that i was at the same percentage at the end of the day with the fat battery as with the orignal one. So i just have this fat battery with me in case of an ermergency or so. My original battery now last 3 days for me so i can deal with that, i don´t use it that often.
I would not buy it for a second time, even tho it is really cheap.
So why will they sell this huge brick and it is no better than the flat original battery? hmmmm... :-?
To make money, and it works
You can buy two spare standard batteries and charger for around $12US on ebay, and I find it quite easy to just have a charged spare in my pocket for when I am out and about, and one still on charge ready for when I get home in case I need it.
For me it has been an improvement. I have more protected the camra and now the life expectancy is slightly higher than 40%
size of ext.battery
Could anybody post a photo of HD2+ext.bat or write in mm width of exserted battery.
if you are honestly going the route of the ugly ugly extended battery back cover and all.. why not just get an official htc.. so quality wouldn't be an issue????
Because the HTC one still isn't available.

The width of the battery is 52mm the thickness is 10mm and the lenght is 45mm
The 2150mah is a wonderful wonderful battery. I am glad to own it, and for really heavy users, or those will be out and about all day, it is definitely a great investment ... so long as you are ok not having a case.
But I started to think about it and realized, having 68% left at the end of the day is wonderful, but do I *need* 68% at the end of the day just so that I can risk damage to the phone? I don't think so.
With the low-effort battery charging trick (charge with power-on, when green, select power off, and wait for green again; NO NEED TO UNPLUG), the 1750mah provides a full day of usage, but will fit in a case.
Anyway, while YMMV, I think the bragging rights on battery power do not outweigh the risks of damage.
My 2 cents.
FWIW, you could do this and still have a case protecting most of the phone.
http://forum.xda-developers.com/showthread.php?t=703332
yah i like extended batteries but i dont want to sacrifice the case
Welp
Well ... I did a proper charge this morning, and played with Nav, maps, a few games of freecell, emailing, 1 phone call, and am still at 74% with my 1750. I think the 1750 with proper charging is the sweet spot.
Will the Innocase fit over the phone with a 2150 if you have the battery cover off?
For what it's worth, I bought the 2150 and, following the advice I received from another xda thread, just cut the back panel out of a soft case. Though much of the new expanded battery back is exposed, the camera lense is actually much more protected than before. And, of course, the screen is now protected from dropping. As a bonus, the phone looks nicer and the obnoxious bulge is considerably less noticeable.

I did the exact same thing. If you take your time and pay attention to detail the end result is very nice.
I did the hard case and cut it. 17 hours of use and still has half of the charge.

Thank you for your 2 cents, it has earned interest.
I was considering which battery to get since the stock 1300 seems to last ALLLLLMOST the whole day for me with heavy usage and having it plugged into USB at intervals when I am at my desk. I need something to last all day or nearly so without plugging in at all. I prefer to stick with something that fits in the stock case so I'll go for the 1750.
Thanks for sharing!

I guess that I am a moron. I don't get what the low-effort battery charging trick does. What do you mean by no need to unplug? I understand the steps, but don't you need to unplug it when you go somewhere?
I just bought the 2150 the other day and I did everything I could think of yesterday to completely kill it. I had it off the charger all day at work (I usually keep it plugged it at work), I played slacker for about 4 hours a few of which were in my car and didnt use my car charger (I always have my phone plugged in when driving), played about an hour of "traffic jam", sent numerous texts, talked over bluetooth, had GPS on all day, and lastly used SportyPal for an hour when I put in my bike miles. After all that and 15 hours later I was finally in the yellow. With that said I do love the extra juice I get from the battery but I dont think I need it over the 1750. I am going to order the 1750 and see how that holds up. If I like it I will return my 2150.
Anybody have a good and semi cheap case idea for extended batteries? Or pouch
Well... so far I've ordered a 3500mah extended battery from Hong Kong.. but as I believe this will take rather a long time to get here... I've ordered another one from the UK as well from ECELL, which apparently has a silver extended cover.
I'm well aware that these are likely cack batteries and I have a plan for that
Basically I'm hoping that whichever one I consider to be the worst will either die on me... or I will simply end it's life prematurely. I am going to cut open the battery (Carefully!) and try to replace the cell's with two Genuine OEM 1500 mah batteries, for a true 3000mah. I bit elaborate but I think it should be possible as long as I cut in the right places.
EDIT: I found genuine LG batteries for about £8.50 each plus about £5 postage, so will order 2 batteries for around £22. They are special order though, so will take 14-28 days. (I am also getting them to confirm the capacity is defo 1500mah, as no point buying them otherwise.)
Update: Images in post #29 : http://forum.xda-developers.com/showpost.php?p=23120430&postcount=29
Well.. I was getting a little impatient... so when I was really tired (and may just a little to drink), I ordered one from ECELL on ebay. It had a silver cover and a 3600mah battery (We all know it isn't that much), and was listed for the 2x P990. Turns up.. it's for the LG Optimus S :-( Bummer. Just trying to get a return/refund.
So... experiment is delayed somewhat.
Update: Two LG OEM batteries have been ordered ; The incorrect extended battery sent back ; Still awaiting the HK Extended battery. Bizarrely I thought I actually ordered a 2nd UK based battery.. but I was so tired I think I forgot to do it lol. Can't wait to have a play with these
Refund form ECELL given without issue Have now received the 3500mah battery, and just running that to see how thing's are with it. I am waiting on the two OEM batteries to turn up from LG before I can start modding this extended battery.
Since I also have a bigger case now, I am going to look to see if I can play around with an external antenna as well.. and maybe fit a bigger antenna inside the expanded case. With that in mind I have ordered two antenna's of different types to see which one fits (expensive.. but then at least we all know )
Sounds really interesting.. keep us updated please!

i got the 2400Mah battery(2 days of usage) i'm looking forward for you're results
specially the modded one pictures will also be great if u can.
thanks!
Apparently the LG batteries have been dispatched now, so should get them within a few days. Only annoying thing is that even LG were unable to confirm whether these batteries I'm getting are 1500mah. I will be gutted if they are not lol.
btw.. you should see my desk at present at home. I have about 5 phones, four of them in bits awaiting tinkering, LED bike lights (all modified), circuit boards from laptops everywhere, reparing a 4x 18650 battery pack + routers etc lol. And I just realised that I actually don't know where my soldering iron is ROFL. Must dig one out.
Anyway... I'm looking forward to it and if I can get it working, I'll put up pics etc. I'm very interested in trying to get the temp sensor working (although I realise it may only work for one of the batteries.).
P.s. as for extended cases and covers I bought this w w w.ebay.co.uk/itm/Clear-Black-Trim-Rubber-Case-Cover-LCD-Film-Pro-LG-Optimus-2X-G2X-/180782656771?pt=UK_MobilePhones_MobilePhonesCasesP ouches&hash=item2a177c6d03 and then cut out the back clear part. It's not a perfect fit, but it will work for the moment (Buy at your own risk.. I actually stretched mine too much when getting the clear part out).
Genuine LG batteries have just arrived about 30 seconds ago. They are 1500mah
So with the delivery charge added in they were £11.04 each (£8.49 each without delivery charge). So if you ordered more it would be less due to the one time delivery charge of £5.10. Not bad for a 1500mah genuine battery! Batteries dated 10/09/2011.

Yes. I've now ordered a second "3500" mah battery so I have a spare cover and shell in case I **** anything up. I am just trying to gauge the capacity of the 3500 battery. On my first run it lastest almost 2 days on stock rom, with a fair amount of use. I would prob say only around 2000mah at a guess though.
I'm just trying to get it to run down again for a 2nd charge now.
Once all that's done, I'll open it up and start tinkering I will have to get both the LG batteries to the same state of charge as well (same voltage level) before hooking them up.)
Bear in mind I've spent £22 on original batteries that I am about to hack open for the cells inside, so there is no going back lol. Pretty expensive mistake if I **** it up relatively speaking.

no doubt it could be an expensive mistake, but if u succeed which i think you will the results will be probably a 4 day battery. so i think its worth it
i got the 2450Mah battery and it holds about 2 days with medium usage, so im really thrilled about ure test as i dont care about the size of the phone,
if you can share pictures it will be great you can also p.m if u want!!
thanks.
Shpapy.
No problem, will do
I charged the battery again last night, and rapid drained it running bluetooth (nothing connected), some GPS usage and wifi with smartshare running a video across from my NAS drive. In the morning it was down to about 25 percent so tried GPS on cycle to work and then drained it with music and GPS until 1%. Charged it without using it, and it's reporting about 1900mah estimated for the battery. I don't rate the estimator as highly accurate btw, but it's a guide .
I will try to take the battery apart tonight if I can. Not sure on best way to open it though, as I will need to reuse the carcass.
Damn.. was taking it apart and fried the circuit it came with. Unfortunately the metal legs that bring power from either side slipped off and touch the outer shell of the battery, was enough for a small yellow spark :-( oh well. (EDIT: Hmm.. circuit may still be alive actually...)
It's two batteries pressed together with several layers of thin plastic between them, either for insulation, spacing or both. I'm actually pretty surprised the cells weren't isolated better from each other.
Update 1: Well, for the first time.. I just managed to burn myself with electricity opps. These packs are really badly isolated. Shorted it on the tip of my finger... beginning to hurt lol. There are NO ratings on these batteries whatsoever. However, one thing they are is... amazingly well balanced. Just measured them and they are both exactly 3.78V's.
Update 2: The circuit and LG Battery will NOT fit directly into the old casing. There will need to either a mod to the extended casing, or we'll just have to 'go without', and make a casing up. It's looking like it's best to do without using the old battery at all actually, and just wire the two batteries together using the LG circuitry. (Well only one of the circuits).
Update 3: Will dig out the soldering iron tonight and get this double battery running
Update 4: Have VERY BADLY soldered the batteries together and combined battery is now charging in the phone. Due to the excess solder on the sides the battery is not quite proper fit, so I will have to redo it at some point. Really very dissappointed with how awful the soldering is, I will simply HAVE to redo it once this experiment is tested. Any tips on a soldering iron chaps? On the plus side, the one thing I do get is a temperature reading :-D
Tip number 1: Quickly snip the circuit off first and DO NOT let it touch the side of the battery casing, it will short out.
TIp number 2: h t t p://www.technfun.com/pages/article.php?id=22 Excellent guide. Take note of the safety tip!!!!
Points of interest
A) The extended battery is EXACTLY double the width of an LG battery.
B) LG OEM Batteries are made by Sanyo
C) Don't use a conventional soldering iron... it is almost impossible to solder the negative side and you will end up overheating the battery if you are not careful. (Any tips here guys?)
Charge battery up last night, and stayed up wayy too late trying to drain it.
Technique... used the 'flashlight' app to keep the LED on, turned on bluetooth, turned on wifi, and use smartshare to stream a movie (at full screen brightness) to the phone. Played Dungeon Defenders for a while as well at full brighness so hopefully the graphics core would take more power. Battery Temp got as high as 40C under 1400mah draw. Odd thing was that battery widget pro at times reported +25000 Mah(ish), yes PLUS '+', and 25000mah, that's just insane..not sure where it was getting the figures from :-(
7% battery left when I put it down, voltage was 3.550 or very close. This morning, voltage it still had 7% left and voltage had increased to 3.7 ish. Guessing it's because the battery was warm last night when under heavy strain, and now it's relaxed and cooled it's feeling better lol. (Or maybe something else?)
Running gps client down now in attempt to drain the rest before recharging. Ideally want to get it down to 1% before a full charge.

cool progress , can we get some pictures of the new battery?
how were u able to fit it in? i get u got a bigger case but still....
share with us ure images / knowledge its sounds really cool doing.
I basically copied what they had done on the 3500mah battery, and merely connected up the positive to positive and negative to negative terminals of the batteries using thin strips of metal, and only used one circuit from the LG battery. Basically I parallel the batteries to increase capacity.
I used a small spacer to keep the batteries seperated, but thinking about it, I could have use the bodies themselves as the 'negative' but it wouldn't have been a good connection). I then just taped the battery up and use the 3500mah battery sticker to hold it all together.
This really is just a 'prove it works' / prototype, and I will remake it neater, although I may have to buy a better soldering iron.
Pics later.
Note: After charging back up from 1% this morning to 100%, the 'estimated' mah by Battery Widget Pro is 1551mah. This would indicate to me that one battery is not connected properly unfortunately. I'm gonna run the battery and see how long it lasts under general usage. If it lasts only a day and a half, then I suspect I will have to resolder.
I bought a 3500mah half a year back and it wasn't any good. Twice the width but lasts the same as the original one. It'll be good if you could show us some pictures? I may consider making one too!
To be fair the estimated capacity of the 3500mah was around 1800 to 2000 mah. Pretty good considering it came with an extended back cover for under £5. It does seem entirely random though, and I was never comfortable without a temperature sensor.
The work I have done so far is rubbish to be honest. I thought I'd make a better job of soldering. I will have to redo it, as the fit is terrible due to the solder being too big/messy, and the connections are not very or or not working/broken.
Can't wait to see the results.

For some reason, battery widget pro was recording very high mah draw/drain. I do not believe I soldered the negative terminals well enough. I took it apart and tried to prise a little flap of metal up for soldering, and managed to rip the terminal off the pack. I will do my best to remedy this of course and let you chaps know the result.
I also have the 3500 mAH and I was wondering if it was really giving 3500 mAH. I'm getting about 1.5 days on this battery with moderate usage. Heavy usage I get about a day. I wonder what I'm doing wrong. I think it's supposed to last longer.
Hello all, I got a no-name 3600 MAH battery off of Ebay for 9.99, this one here and I wanted to say that it's been mostly good. It says that the seller ships from China but it actually came from within the US and came fast.
I have used this in my primary ATT model XP for about a month now. Thankfully this battery is genuinely more powerful than the stock battery. I don't know if it's 3600 Mah in reality but I estimate it holds a charge for at least 2x as long as the stock battery. I took a 3+ hour drive a few days ago with the GPS on with the screen mostly on and it only dropped from roughly 85% to 62%. It adds alot of weight to the unit and almost doubles the thickness, making it a far less elegant phone but arguably a more comfortable game pad; I do find the L and R buttons are less accessible, however. The battery back is plain piano black with no markings and apparently adequate cutouts for the flash and camera.
THRICE the phone has died without notice, with reasonable battery life remaining. Honestly this happened maybe just as much with the stock battery. The previous owner abused the phone a fair bit and I am tempted to chalk it up to that.
My biggest problem is that the extra weight seems to all be carried by the flex cable. If you pick up your XP by the screen half, which is a very casual, reasonable, and natural thing to do under normal circumstances, you're putting significantly more weight on the flex cable than it was ever meant to bear. There's nothing an aftermarket battery manufacturer can do about this I suppose, and sadly it affects all slider phones along the same lines.
Another big issue is that the channeling for the speakers is complete ****. Instead of coming out the bottom and being directed toward the user as is the case with the stock battery cover, this battery cover causes the sound to echo around inside and then leak out in every direction. It's not a deal breaker but is something to note.
Worth a tenner.
Last year I bought two of 'em (were around $11, the second one was a bonus), same maker, same model. Still rocking, nothing to complain about. Passed every test I threw at it (heat, overclock, stress, charge cycle, etc)
nice..
Lol no weight is put on the flex cable the slider is what holds the weight lmao has a stopper on both ends also to keep it from sliding out of the slider.

So I got one of these at the start of the year. Is it just my imagination or does it charge slightly lessen after 11 months? I could be wrong, but it seems to drain more quickly. Would love to know other people's thoughts.
Great
