4 out of 5 eggsGreat product, use standard W10 drivers

Pros: Plug in and use, don't bother installing the IOGear drivers

Cons: IOGear drivers are buggy, I had to remove them before this would work

Other Thoughts: I deducted a star because of the driver issue. Running on Windows 10, the IOGear drivers don't work.

Manufacturer Response:

Thank you for choosing IOGEAR . The GBU521 drivers have been tested and work with Windows 10. There may be a driver issue with the Bluetooth stack on your computer if you upgraded to Windows 10 from a previous operating system. The GBU521 is also plug and play with Windows 10. Once again, thank you for choosing IOGEAR.

1 out of 5 eggsWindows 10 support missing

Pros: - Instructions on installing driver were clear from directions
- Timely delivery

Cons: - Windows 10 driver simply didn't work with device
- Driver hung trying to disconnect device
- Driver blue-screened Windows 10 100% of time when device tried to connect directly

Other Thoughts: - The device (headphones) work flawlessly with two other bluetooth adapters (PC and phone)

1 out of 5 eggsBluetooth devices show up as "Unkown" and pairing doesn't work (Windows 10)

Pros: Can't think of any.

Cons: When I search for devices (on Windows 10), I get a list of "Unknown" devices. I tried pairing with some of them, and that failed. I search online and tried to fix this "Unknown" bluetooth devices list problem, but haven't been able to. :(

Windows auto-download a driver, but after it didn't work, I tried installing the 150MB driver from their website, and it didn't make any difference.

I am going to have to buy another bluetooth adapter now.

Other Thoughts: I honestly don't know why IOGear's driver (from their website) is ~150 MB. I have a feeling it is carrying malware. Windows automatically downloads a driver when you first plug it in. After installing the driver from their website, I looked at Device Manager, and nothing had been changed. All the more reason to suspect their 150 MB "driver" is actually some kind of malicious software.

Manufacturer Response:

Thank you for choosing IOGEAR and we apologize for the inconvenience. The GBU521 driver package is 138 meg however this has been thoroughly tested and we can assure you there is no malware. This is an untrue statement. The GBU521 will also work plug and play with Windows 10. Once again, thank you for choosing IOGEAR.

2 out of 5 eggsCould be better on Windows 10

Pros: The connection works great. Gives good range on my LG headset. I was able to leave my bedroom in the back of the house and go to the front of the house without it disconnecting. Connects automatically when my computer turns on.

Cons: It was hard to put the connector into the computer. Doesn't work with USB 3.0 connector. If the bluetooth headset is not connected before the computer turns on windows 10 gives an error and starts to restart.

Other Thoughts: Be careful with this one. The connection is strong but there are a lot of errors that needs to be fix with a firmware update or something.

Manufacturer Response:

Thank you for choosing IOGEAR . The GBU521 is a class 2 Bluetooth device. Most class 2 Bluetooth devices are USB 2.0 . The GBU521 has been tested with windows 10. Both the software and the GBU521 work with Windows 10. Your comments will be forwarded to a product manager for review. Once again, thank you for choosing IOGEAR.
