For the price you can not really s' to complain. Samsung official said? j 'expresses doubt as to the quality of finish compared to an official Samsung store n' is that by far the reality. Not the same material on the cover and the back cover of plastic is not super finish, bubbles in the plastic ... Moreover the casing is more easily scratched than the official cover Samsung.
For the price you do not go too s' to complain, but avoid saying that it's an official Samsung product (you not believe him when receiving).
