Ratings & Reviews+

BLUETOOTH 4.0 USB MICRO ADAPTER (GBU521W6) is rated 4.1 out of 5 by 189.
Rated 5 out of 5 by from Perfect 10 out of 10 I was skeptical at first about the transfer speed but it really pulled through. WHAT YOU GET: CD FOR DRIVERS AND USB ADAPTER. - Very small wont take up space. - Connect up to 4 devices at once. - Very Affordable. - Transfer more than 1 file at a time (Other bluetooth usb will only allow 1 file at a time) - SIMPLE TO INSTALL USUALLY JUST PLUG AND PLAY. Unless your computer asks for drivers which the cd already came with. - If your desktop or laptop does NOT have bluetooth, this usb will give you bluetooth funtionality using authentic windows drivers NOT a 3rd party driver or seperate program to transfer files. I CANT COMPLAIN ABOUT THIS PRODUCT VERY AFFORDABLE AND FAST!!!!

Rated 5 out of 5 by from bluetooth adapter my biggest concern when i ordered this item was whether it would work properly with Windows-10. No problem. drivers were already present so all i did was plug n play. primary use is to access a bluetooth speaker.

Rated 5 out of 5 by from Secret to a good (Tower) Mac Pro The Bluetooth in the pre 2013 Mac Pro (The towers) in bad, really bad. This bluetooth adapter uses the same chipset as new apple bluetooth adapters and just works. Plug it in and you have much better bluetooth than you did before. No drivers, just re-pair your devices and enjoy.

Rated 5 out of 5 by from So far, so good. Not a problem I see that most of the reviews are outdated (2013 - 2014). I just bought my dongle in August of 2017 and am quite happy with it. It did not come with a cd so I had to go to the manufacturer's website to download the drivers (so easy) and the upside to this is that I didn't receive any "bloatware" that all of the other reviewers are complaining about. I guess IOGear listened and remedied the situation. After installing the drivers for my OS (Windows 8.1) the functionality was clear. I simply located my Devices and Printers tab in Control Panel and "installed a new device" and it found my bluetooth speaker (switched on) and I was good to go. Easy peasey.
