Nice Battery
Well I have to say this is a very good extended battery at-lease from my day use of it. it wasn't even charged fully (might have been 30% on extended battery when received.) and I went from 3:00 pm to 10:00 pm and still had 95% of my normal battery when I got home. The case fits over the Samsung Galaxy S II perfectly real nice. if you want a size comparison; with the phone inside the case its no Thicker then a Samsung Galaxy Prevail from the side so it doesn't make the phone as thick as I thought it would be. I -1 star because the only issue is that the case keeps charging the phone so every now and then you will hear the "battery full" sound beep. I'm sure there is a way to fix it but I'm not going to trouble myself. All in All I say its a very good Extend battery for me, it last me a very long time and I'm a power user. I rather have this then those Cheapo Extended Batteries on Ebay. Side note: The case is matte not gloss like in the picture

Could be better, still best battery solution
To answer previous reviewer, the reason why it enters a recharge cycle is because the case does not perfectly fit the phone. I added a bit of electrical tape at the top portion of the case and now my contact is perfect, it's roughly 1-2 mm off. This is not a battery expansion it's an external battery that will recharge your internal battery, so people should expect the internal battery life to die faster since your constantly recharging your phone so expect to change the internal battery under 1 year of usage. Gave me an extra day on light usage, help me finished my day on heavy usage so I can't complain. Costs too much but still the best battery solution quality wise.
