Review on 🔌 Monoprice 113749 Select Series USB 3.0 A to A Female Extension Cable 1.5ft for PlayStation, Xbox, Oculus VR, USB Flash Drive, Card Reader, Hard Drive, Keyboard, Printer, Camera and More! by Patrick Reid

Bought two and connected together to increase the length to 12ft instead of 6ft and it only works if you use it alone as a 6ft cable instead of them connect together to extend them to 12 feet in length. I have a 10-port USB hub and my external hard drives don't show up when connected. However when used individually it shows all 6 of my external hard drives but when combined it only shows 2 of them which defeats the purpose. So I'm sending them back.
