The work from Benson Leung shows that ~ 30% of USB-C cables that fail his standards testing. His work has also encouraged a lot of other individuals to do testing. There are quite a few websites popping up in response to this such as: usbccompliant.co.uk (UK/EU) & usbccompliant.com (US).The sites have already been listing the "compliant" cables on Amazon - but It is good to see Amazon taking accountability themselves.
