Received the first battery was not working. The second worked for 15 days, then when the power in charge she started to be heated to the point where she did expand the screen of my iPhone, the problem is that if I had not I think this was the phone could catch fire.
Conclusion Now I have to change the screen and battery.
These batteries are compliant to the M .... it's amazing that we put on sale this type of product into believing that they are Apple products.
