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.
Does not work to connect to imac thunderbolt port as display adapter. Tried off my dell xps 13, and cannot get the Imac to go into target display mode.
