Nothing really modded yet. But price was farely cheap and shipping super fast. Backcover is only a bit flimsy, matte and fingerprint-proof. Dunno about battery yet, but it says 3500mAh. Jihuu! extra 500mAh.. or not.
Battery lasted 92h with ~3h display on. Neat
This battery is full of crap, i dont recommend it. its pretty much useless right now.
