    I already have it and it is fantastic. Adds a lot of weight of course but instead of charging daily I only need to charge every 3rd day. There is a problem with the back cover. The power button is very hard to use. I emailed Seidio and am waiting for a response.

    I am hesitant to order due to the power button problems. I am curious to hear their response to you.

    I just called Seidio tech support about the power button issue and they said that it would get easier to press over time. Essentially working itself out. I guess time will tell.

    mobilecityonline.com has both batteries for $10 cheaper. i preordered the 3400 mah because im thinking the 4000 mah will make the phone too bulky.i don't mind charging my phone every night,i would just like to make it through one freaking day without having to worry about my phone dying. i wish there were pics of both backings side by side so i can see if i should change my order to the 4000 mah. its only 5 dollars more.

    Hello,

    Just wanted to let you know that the backings are the same for both batteries - the 3400 mAh and the 4000 mAh. There are no physical differences between the two.

    I was looking at the 3400mah one on mobilecityonline.com and it doesn't appear to add any bulk to the phone, can anyone confirm this. I had the 3500mah extended battery for the Evo 4g and it was a monster. Thanks in advanced.
