Review on Anker USB C Cable (2-Pack 6ft): Powerline USB C to USB 3.0 Cable for Galaxy Note 8, S8, S9, MacBook and More by Chad Siofele

I bought these to use with my USB-C fast chargers. Don't really use them for data transfer, so I can't rate them in that department. You are quite significant. I will say one of them didn't work for me but Anker replaced it and just asked me to do some troubleshooting steps and send them a picture. A return was not necessary. I've had good luck with Anker in the past, their products seem to be well made, they back them up and replace them when they fail without undue burden on the customer. Everyone I know has had the same experience. I'm writing this review because Anker customer service asked me to, but they deserve it ;)
