This thing fits in the USB port and is tiny. It works really well. My PC downloaded and installed the needed software. This dongle has a great signal, the throughput as excellent and the speed of the dongle was super. it connects quickly and was easy to configure. Overall a nice, neat, fast, low cost, Bluetooth adapter.

The Bluetooth Dongle Works Well

I wanted to be able to bluetooth my PC to a set of headphones but the PC didn't have it built-in. The dongle from Avantree works well and has more strength than I expected - I can get the signal from the far end of my apartment.
