I use this cable for connecting a 4k HDR monitor to a MacBook Pro and it works great. Good quality, around 4mm thick, well finished around the plug ends, and high quality materials by the look and feel of it. I initially ordered one brand, then another (via Amazon) then a Belkin one (via Amazon), then another direct, but you need to read the small print to ensure compatibility with up to date computer systems / laptops, the Belkin cable was only compatible with iMac (2017) and not a Macbook Pro. None were fully compatible or performed as expected. After a bit of research I discovered Thomann and ordered this Delock Thunderbolt Cable (2m). It works perfect. Just ordered another to run to an SSD external drive (I first tested using the cable I had). Again, works great. Highly recommended. Thomann customer service seems great and prompt international delivery too.
