Review: Very good usb bluetooth adapter for linux. Worth the money. - Works flawlessly with Arch Linux. I use it for my Bluetooth earbuds, have not tried file transfers yet. It has genuine CSR chip & hence a bit pricey compared to other fake Chinese clones. But very much worth the money. Other users have reported audio issues, but that has nothing to do with the adapter itself. Those audio issues they reported are to do with Pulseaudio utility. I'm very much happy with this product.
Review: Great product. But don't install software from cd. It slowed my system. - Cd Installed software made my computer run slow. Alternately I was able to use it with no prior software installation. Just connected to usb and it worked! Nice handy design and good quality. Good performance , never slowed the my headset connected thru it

### ⭐⭐⭐⭐ Good quality, ease of use (windows 10)
*by N***T on 9 June 2020*

Absolutely no issues with Windows 10.. gets auto detected and drivers gets installed.. rest it's breeze. Range is good as well. Haven't used in Linux yet.. price was but in higher side compared to others but may be that's due to the chipsets used due to which it works so seamlessly
