This does everything I needed, good range and allows connectivity of Bluetooth speaker and Controllers, nice small profile item too for use in a laptop which getting caught easily, would highly recommend!

Was looking to pair my bluetooth headphones with my Windows PC (no BT adapter). Saw this advertised and, having used TP-Link products before, had no hesitation in buying it. And it didn't disappoint. - No set-up issues - plugged it in and off we went. - No lagging - perfect sync with YouTube videos etc. I have no hesitation in recommending this if you're looking for a bluetooth adapter.

Quality brand works faultlessly first and every time, great product.
