An ex. This battery type I obtained from the marketplace. The wrapped in black-silver foil with "100% Premium Quality", but without giving labeled for origin and battery capacity also contributed a QC sticker from 03/2008, so it was not quite factory fresh. Because of a lack of fit he could only with difficulty using the phone. Above all, he is too thick, so that the battery compartment cover of V3razr is pushed to the sides and unclean closes. I give the item back.
