Was able to replace my battery with minimal difficulty (removing the adhesive on the old battery is a pain). Tools I got met all my needs. Only comlaint I have is with the replacement adhesive that came with the battery, it wasn't entirely clear what direction I was meant to lay the adhesive, and it also didn't come with the layer of final release liners, so the adhesive was sticking to stuff while I was reassembling, and also stuck to the blue backing layer when I was trying to remove that after applying it, lifting off the phone in some areas, that was troublesome. That's the only reason this review isn't five stars. Other than that, the battery is working well, will probably come here again in five years when I need another new battery.
