Original product for Samsung galaxy S3 phone containing an extra battery, a charger, two shells and a flip case (opening way "book" is) that attaches replacing the original hull back of the camera . All products are 100% samsung and therefore adapt perfectly to the phone. Second essential battery. The charger allows for constantly second charged battery. For cons, the kit does not include (and this is a shame) the cord that connects the charger to the socket, so you use the original cable supplied with the phone. After a full month of use, I am quite satisfied with this kit that seems to me essential and a good price / quality ratio (37).
