My original battery no longer held the office, he had swollen and risked explosion !!! To compare with the nine I realize the difference and the risk The battery seems to be an original product of Samsung brand with good reference, so no complaints I'm satisfied (according to the photo and references). Remains to be seen in the long term it will hold the load and commitments. Shipping is very serious in recommended it poses to La Poste but that's not the worst! The most important is to have a battery in line with what I expected. I recommend the seller and product.
