It is a new Bluetooth adapter which supports Bluetooth v4.0.
Let’s have a look at the package first. Oh, no. I still want to see the difference between Bluetooth 4.0 and its previous generation, such as v3.0, etc.

It provides a CD with drivers.
Before I install the shipped driver. The Windows 10 uses its default driver.

The adapter is white. Looks cool when it has white light on it.
I have to tell you why I need a Bluetooth adapter on my desktop. Not for its data transfer feature.
Actually, I need it for my Fitbit device and other Bluetooth accessories.
