The cable doesn't work on my computer. I bought a different brand from another retailer and it worked.

Working just fine with my XPS 13" attached to an HP Graphics Accelerator Shell.

Will update once I start using it with a true 40 Gbps machine.

Tried both the 1.5m and 2.0m length cables to connect ThinkPad X1 (which has two, 40Gb/s, 'four-lane' TB3 ports) to a Sonnet Breakaway Box 550 with an EVGA SC 1060-6GB GeForce card inside. While this setup works well with Sonnet's 0.5m long thunderbolt cable, the Monoprice cables both failed to make any useful connection.

More info’: Two devices are normally initialized when plugging-in the breakaway box signaled by the Windows "device connected" chime... "Video controller" and "HD audio bus" appear in the "safely remove hardware" tray icon menu when all is well. Using either Monoprice cable, I hear one "device connected" tone (maybe for audio bus?) but video controller is not initialized, display remains in standby (dark) and Window 10 is not happy as it seems to keep trying to connect but never succeeds.

Other thoughts: First of all, Monoprice is my preferred brand for firewire, thunderbolt and high-bandwidth video cables. I had a similar experience as outlined above with a 1.0m long active TB cable from another mfr'... After updating ThinkPad thunderbolt firmware from v30 to v33 (as recomm. by other cable mfr' support staff) connection did improve, but I felt there's still some instability (in the form of video glitches) even using that 1.0m long cable. I've resigned myself to the fact that 40Gb/s TB3 cables are limited to 0.5m long for a reason, and have rearranged my work area to accommodate the eGPU nearer to the ThinkPad.

No issues with shipping. I've been using it almost daily for a few weeks now with my eGPU setup and it been performing flawlessly so far. I'm quite happy with the experience and the cable's performance.

Generous length, no complications, and both & feels high quality. When it comes to cables monoprice is my go to and they have never disappointed. It also works flawlessly with my EGPU, and there's been no blips or stutters.
