Rated 5 out of 5 by from Works good after dificult install. Had difficulty getting the UB400 to connect to my new headset. The UB400 is Bluetooth 4.0 and my headset is Bluetooth 5.0. It easily paried with other Bluetooth 4.0 devices but took alot of reboots and effort to connect to my new headset. Once it did pair it has been working great.

Rated 5 out of 5 by from Awesome bluetooth adapter I had a generic bluetooth dongle and had frequent issues with my Xbox One controller + Headset on Windows. All problems were solved with this TPLink adapter. Range is far better, and the quality of the connection is impressive. I totally recommend.
