I have read in advance the reviews pointed this out, that the battery is not an original. However, there were also positive reviews here, I bought it. In my phone but the battery does not work, then I have returned to the seller with a request, with optional replace the battery, or refund the money. But I have not received any feedback from the dealer. Since the rear end has also cost 1.50 one can say the bottom line, 10 away.
