Review on Wireless Bluetooth USB Adapter Dongle for Laptop PC, Compatible with Windows 10, 8, 7, Vista, XP, Supports Mouse, Keyboard, Headset by Mari Hall

I bought this to pair my Logitech K380 keyboard with computers in the computer lab at school and it works great. Computers run Windows 10, so you can connect Bluetooth without installing drivers. I plugged the dongle into the computer, went into settings and connected the keyboard as if the computer had its own bluetooth. If you don't have a Windows 10 computer, you may need to install drivers, but this dongle comes with 80mm. driver disk if you need it. The dongle is also small, but not too big. Logitech merging receivers are very small and difficult to remove from a computer. In my case, if I connect the key to a public computer, I need to be able to disconnect it easily. This key is big enough that I can easily turn it off. If I had to find something negative about it, it would be that the blue status light gets annoying quickly. It blinks to let you know it's on a Bluetooth transmission, meaning there's no doubt as to whether it's working or not, but it never stops blinking, which I think can get annoying quickly , if it is on the laptop in a dark room. Otherwise this key is excellent. I haven't noticed any drop in connection speed compared to a 2.4GHz wireless connection, which can interfere with other wireless connections. That being said, I don't think anyone else in the lab is using a computer with Bluetooth, so I'm in an optimal environment.
