Works great, literal plug and play setup. Used with my 2020 MacBook pro 13" to speed up rendering times in Blender and make DaVinci Resolve snappier. Works a treat with my old Sapphire Radeon RX480 Nitro+. Now have it set up on my desk with a second monitor plugged in, to charge the MacBook when I'm working at home. I use a slightly longer 3rd party thunderbolt 3 cable than the tiny one supplied. VERY occasional glitches, probably more MacOS than this specific device from the looks.
