### ⭐⭐ 2.0 out of 5 stars







  
  
    Doesn't work on Windows 10
  

*by U***E on Reviewed in the United Arab Emirates on 2 June 2020*

I have tried using every driver available for this and it still didn't work. Shows a Bluetooth signal on some drivers but doesn't connect to a Bluetooth speaker or an Xbox controller. On the driver windows defaults to, it doesn't show up at all.

### ⭐⭐⭐⭐⭐ 







  
  
    Great value
  

*by M***E on Reviewed in Canada on 4 November 2023*

This helped me connect an old PC (Windows 10) without bluetooth to a wireless Apple keyboard and mouse (also older). It was cheap, delivered next day, and connected right away. It took a while to figure out how to enable all the features on the KB/Mouse but figured it out with the right drivers. It did create some wake issues but I'm pretty sure it's not related to the adapter itself.

### ⭐⭐⭐⭐⭐ 







  
  
    Improved Audio Quality for Laptop
  

*by E***R on Reviewed in the United States on 24 April 2023*

I recently purchased the Onvian USB Bluetooth Adapter for my wife's laptop, and I'm happy to report that it works great! This small and inexpensive adapter allowed us to connect an old laptop to our Bluetooth speakers without any hassle.Before purchasing the adapter, the audio from my wife's laptop sounded terrible when she tried to play her exercise videos. But with this adapter, she can now connect her laptop to her nice Bluetooth speaker that she previously only used with her phone. The audio quality is now crystal clear, and she's able to enjoy her exercise videos without any issues.One of the best things about this adapter is that it's very easy to use. We didn't need to install any drivers on our Windows 10 laptop; simply plug the adapter into a USB port and it's ready to use.
