Nope, or if so my royalty/referral checks never showed up :)
I bought mine back in March of last year and used it to "process" all my cables and was just a happy customer. I've been watching this space (cable testers) for years (on and off) and wasn't interested in the "raw circuit board with led"-versions so once a nicer version came out at a price point I found tolerable I got one.
It's nice to have all my cables organized now (h/t to Akro mills bins, those are a dangerous rabbit hole) and now instead of just buying a new cable [0] when I need one I can go grab one that matches the specs I need.
[0] Call it wasteful, call it lazy, but when faced with "I have a cable that fits the hole and is the right length but I don't know what it's capabilities are" I would often just buy a new cable with the specs I needed/wanted rather than using an "unknown" cable.
