Product nothing wrong, this is not of very good quality but that's normal considering the price, so excellent quality / price this is what I wanted. Only problem: I ordered 12 copies of this article and I had to pay 12 times the shipping costs when I received a package with everything in it ... so 16 ports costs instead of 1.30 I confess to having enough trouble digesting ... and the store does not want to send additional items to offset the shipping costs or reduce them and it's pretty bad ...
