Continue using Thunderbolt 2 with new PCs

Allows using Thunderbolt 2 devices with newer PCs that have Thunderbolt 3 ports. I've tested it and it just works. This adapter does not allow using Thunderbolt 3 devices with Thunderbolt 2 computers though, unlike the much less expensive Apple adapter. Note: For mini DisplayPort, use a USB-C to DisplayPort cable instead.

Great Adapter

Works out of the box and does exactly what the product description says it will do. I ordered this as soon as it was available, and it has solved my problem of connecting TB2 devices to my TB3 port on the Dell XPS computer.
