Review on StarTech.Com 20Gbps Thunderbolt 3 Cable - 3.3Ft/1M - White - 4K 60Hz - Certified TB3 USB-C To USB-C Charger Cord W/ 100W Power Delivery (TBLT3MM1MW),20Gbps - White by Andrew Sticher

As far as reliably delivering a Thunderbolt signal over a longer-than-typical distance for Thunderbolt via a sturdy cable, this is perfectly fine. What makes me a little bit uneasy is that the "mating" of the cable to one of my Thunderbolt 3 devices was extremely weak -- like it didn't "grab on" all the way. I was able to get it to loosely connect and stay in, but if the cable is substantially perturbed or even slightly tugged on, it'll come out.The device I had a problem with is the Apple External Graphics Developer Kit's Sonnet branded external GPU case. I'm not sure if the fault lies with Sonnet or StarTech, but you'd think simple physical issues like correct connectivity would have been resolved with new-generation standards like Thunderbolt 3.
