Just walked in the door from the local verizon store its still on sale just picked up one the sales rep looked at me like i was crazy but scanned it and it came up 24.99. So now charging it and seeing how long it can go. Fits in my otterbox so not really worried about the little bulge at the side. As stated above does feel a little heavier than stock.
For me, had to use the "contra code" to get the cover on. Snapped the top, bottom, left, right. Had to force the left side down again after snapping on the right so there's a slight bulge but not a big deal with a casemate.
Weight: Definitely a noticeable difference in weight. Heavier than before.
Battery life: Don't know if conditioning is necessary but charged phone overnight with phone turned off. I was able to get through 1 day with wifi turned on and fairly heavy usage playing games and surfing the web. I would say at least +1 to 2 hours more. I couldn't say that before with the stock battery. Great find!
