Life's lessons helped me again! I sat in front of my Mac and was frustrated that my USB-C cable connected to my Mac Book Pro wasn't working with my Samsung widescreen monitor. I thought that there was something wrong with the cable used. That's when I came across an article that said it had to be a Thunderbolt 3 USB-C cable. What is that? I wanted to get it working in my home office! Cables are expensive! I turned to Revain for pain relief. This cable is quite long. There are lightning bolts on the ends of the cable identifying it as a Thunderbolt 3 USB-C cable and it fits my needs! Cost and quality were two of my motivators when buying a cable. I noticed that the cables only fit halfway into the Thunderbolt 3 USB-C port, but when rotated the other way, they seem to fit all the way. Time will tell with this cable. I hope we have enough time to return it if other problems arise.
