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

I use it mostly at my desk with my Win7 desktop, although I've also used it on my Win10 Surface Pro 4 tablet. Worked great on both. In the Win7 box I had to install the drivers from the CD that came with it and it was easy to do and everything worked fine after that. In Win10, it is easy to connect via native BT pairing in PC settings. Quality is good if not great (I'm not a super audiophile) and range is decent. I can walk away from the PC for about 15 minutes and get uninterrupted audio. Build quality seems decent. I've been using the device for about 2 months now and have swapped the key between devices and there doesn't seem to be any issues. Given the price, I don't see how anyone can complain.
