See it on the length but the cable looks very solid. I could compare it with a classic cable for charging the phone and the difference is noticeable. With a conventional cable, my such does not fully charge overnight while this is the case here. In terms of transfers, we feel an improvement too. For me, it was to make the screen streaming and actually, it was more fluid with nothing but banging the butt on the ground either;) (but that, in my opinion, this is techno usb limiting the transfer).
In short, I am very happy with my purchase. If you require quality cables, you can go there, it's good! ;)
