FYI, if you live in #Japan you may want to know that #Elecom has a policy of stating that their Ethernet cables are compliant with a given specification, even when they *don't actually* comply and don't meet the requirements.
Maybe skip Elecom the next time you buy Ethernet or USB cables, or anything else that needs to follow a specification to work well.
It's perhaps not a coincidence their Bluetooth mice seem unable to maintain a stable connection, for instance.
