Review on RIITOP USB C to C Cable 100W [5FT, 20Gbps]: Thunderbolt 3 Compatible, PD Fast Charge, 4K Video - Ideal for MacBook Pro, USB-C Monitor, SSD by Shigg Bigbee

I purchased this cable to use with a USB 3.1 Gen 2 Type-C Hard Drive Dock. My computer doesn't even recognize that the dock is connected to this cable. I also connected a portable SSD to my PC with this cable and it connects at rated speed. The maximum cable length for USB 3.1 Gen 2 is "less than 1 meter" (3 feet or less). This is the second brand of 5ft cables I've bought that claims to offer USB 3.1 Gen 2 speeds and failed, although the first connected the dock at USB 2 speeds - got my gear Arranged to work with a 3ft cord.
