Although this product is listed as "Thunderbolt 3 4 ft. Cable", as you can see on the packaging, "Thunderbolt" was not found. Since it's a USB 4 cable, not compatible with Thunderbolt 3 devices, I bought it to connect two Macs together when one was in target disk mode and it wasn't working. If you want a quality Thunderbolt 3 cable, DO NOT BUY THIS. Inaccurate description aside, the cable itself looks good, although I haven't tested it with any USB 4 device.
