Just got my NEW 3500mAh battery for my samsung admire and I'm pretty pleased with it. I bought it off ebat for a little over $10 on Friday and received it monday! It does stick outand make the phone thicker but IMO I think the phone is easier to hold now as there is something to fit in your palm as opposeed to just holding it by the edges. Still a lot smaller than holding a Samsung Galaxy Note haha. I unplugged my phone around 6 am this morning and use it to play mp3s on my drive to and from work(20 mins one way) made some phone calls and texts and used it for browsing the web on my breaks. Also around mid-day i noticed I still had background data turned on which kills the battery. After all that it's 6:20 pm now and battery is still at 80% :) granted I turn data off when not using it and don't have any apps running I think it holds up well and definitely worth the 10 bucks.
