Review on Cable Matters 2-Pack USB 3.0 Coupler Adapter - Female to Female Gender Changer by Alex Mitra

Can't fault it. However, I tried using this for Android (using the phone's charging cable) assuming they would support some sort of USB OTG functionality so I could read data on mobile and unfortunately it doesn't work for those tasks. This or my phone is not compatible with what I want. It didn't work for my intended purpose of purchase anyway, but if you want to use this as a means of connecting various USB devices and see what happens, or somehow want to use this as part of a USB extension, these connectors will work as advertised.
