I bought this as a replacement for the built-in Bluetooth adapter on my Asus motherboard since the one on my motherboard had very poor range Bluetooth 4.x. I also wanted a compatible adapter for my Xbox wireless Bluetooth controller. This adapter exceeded my expectations on its range.. clear all the way to the other end of my house. I didn't have to do anything to install it other than disabling my existing Bluetooth adapter and plugging in the new adapter. It's compatible with all my Bluetooth devices... even let's me connect several Bluetooth devices at once. I highly recommend this adapter.!
