After many connections / disconnections, I have found no dysfunction: no loss of data or unexpected shutdown! The sockets are gold plated well finished (female entirely covered, unlike some first prize) and the crimp is neat. The sheathing is quite flexible, solid, reinforced and armored. Despite three meters of this extension, there is no loss of speed when transferring data between a hard drive 2 '' 1/2 USB3 (approx. 100 Mb / s average) and my PC. Also, I tested with a key and a USB2 USB2 hard drive; the rate of transfer, via the extension on a USB3 socket, just as steady and strong by being plugged directly into a USB2 socket on the PC!
The AmazonBasics delivery is exemplary, very fast, and with monitoring, all in a perfect and really solid packaging! Compare with a branded equivalent, the price is slightly higher, but the quality is there. It can be purchased with confidence!
