I ordered this for my Windows 7 PC, had some issues with it pairing and general irritation with it sounding tinny.  Updated to Windows 10 and it paired right off and sounds great.

Windows 10 detected it automagically.  Works great right out of the box.

Totally simple to install and use (just plug it in and you're done in Win 10).  Plus, it doesn't drop connections like my other Bluetooth USB plug.

Purchased and installed on a Windows 10 home x64 machine without issues. Sounds work immediately. No audio drivers necessary.

I got this to add Bluetooth capability to my older desktop PC.

I am running Windows 10 on this PC, and happily this device is plug and play on Windows 10.

It works great, and I can easily stream music to my Bluetooth speaker!

It's easy to use and sounds amazing! It's kind of annoying how it automatically pairs. But it's not that big of a deal.

Works perfectly in Windows 10, no special setup or drivers required.  I just plugged it in and it worked.

I'm using this to pair a PS4 controller to my PC and it works great.

I've only ever had it run out of batteries over the course of my workday once, and I was listening to music literally all day, quite impressive.  I regularly unpair and repair it between my Samsung S3 mini and my Linux desktop with out issues.  Strangely I have actually experience more issues getting it to pair on my laptop when I boot into Windows 10 preview, but I don't end up doing that often so it doesn't bother me much.

This adapter worked as described and was incredibly easy to install. With Windows 10, all I had to do was plug in the adapter and update the driver in the device manager. Two minutes after unpacking my headset was already paired and working flawlessly. The adapter is also far smaller than I had expected and sits nearly flush with my PC.

Would definitely recommend.

Thus was the perfect solution. Quick and easy and sounds great!!  Worked with new Windows 8. A great upgrade to an older computer

I had speed and connectivity issues in Windows 10 until I updated the driver from the Mediatek website.  Fine after that.

Works exactly as expected. Clear sound quality and no hassle with Win10 ruined Bluetooth capabilities anymore.
