4 out of 5 eggsDecent bluetooth adapter

Pros: Dimly illuminated blue. has acceptable range. does everything that is needed of it. works with linux Mint. plays well with many different devices.

Cons: File transfer is quite slow(sub 100 kilobytes per second) as in it would be faster to send files to a cloud service and back to the target device.

Other Thoughts: Its pretty much a standard bluetooth adapter that uses the microsoft bluetooth stack which i found out doesn't work with newer Wii remotes. This adapter would make subpar choice for someone trying to use wii remotes with windows unless the toshiba bluetooth stack is used

5 out of 5 eggsJust works

Pros: Easy to setup, works as it says, Broadcom chipset

Cons: None really

Other Thoughts: If you're going to use this to stream audio, be sure to install the Broadcom drivers. Not sure if a disc was included with it, didn't even check. Just downloaded the drivers from Broadcom directly, and all of the enhanced BT features became available.

5 out of 5 eggsWorks great with the Bluetooth Headphone

Pros: It works right out of the box. Easy to set up. Paired my bluetooth headphone from Ausdom, had no issue. Completed automatically install the driver in a couple minutes. Paired with my Oneplus phone and it works great as well. It's very small and great price.

Cons: No issue found

1 out of 5 eggsBig disappointment in a small package.

Pros: Price and small size.

Cons: GBU521 BT adapter, the transmitting signal to my BT speaker constantly cuts-out at any range, 10 inches to 10 feet, with a clear line of site! I've had BT Adapters that would go 30 feet through 3 walls. My BT speaker works flawlessly with other BT devices so my speaker is NOT the problem. I made sure I was using the newest drivers available. Also the dongle is hard to insert and extremely hard to remove. One other buyer said his USB port was damaged by this same product, now I understand how that could happen.

Other Thoughts: This is clearly defective and if I want to return it the Return Shipping is almost as much as the product.

Manufacturer Response:

Thank you for choosing IOGEAR and we apologize for the inconvenience. The GBU521 is a class 2 bluetooth so it is not line of site and has a maximum range of 30 feet. The USB is micro size and should not damage the usb port in your computer. This information will be sent to a product manager. If the GBU521 is within the 30 day return windows Amazon will usually swap this straight across for you. If over 30 days it would have to be shipped to IOGEAR, the customer is responsible for the one way shipping here and we pay the shipping back to you. To better service you and understand your set up, please feel to contact our customer support at 1-866-946-4327 or email us: support@iogear.com. Once again, thank you for choosing IOGEAR.

1 out of 5 eggsBad Egg

Pros: None

Cons: Will not connect to Logitech UE Boom wireless speaker that I bought it for. Tried three computers. Tablet and phone can connect to the UE Boom just fine.

Other Thoughts: If anyone knows a working USB Bluetooth adapter with good range, please post the link...

5 out of 5 eggsDoes work with Fedora 21

Pros: I posted an earlier review that said the IOGear didn't work with Fedora, I was wrong it does. It's not plug and play and the GUI tools can't find it until you've configured it with the bluetoothctl command line utility, but once you've done that it works with bluedevil-wizard GUI tool.

I paired it with two audio devices, a set of Bose Bluetooth headphones and a Grace Digital Bluetooth amplifier. It works reliably with both.

Cons: None

Other Thoughts: Setting up the device, use the bluetoothctl command line utitilty,

bluetoothctl

Find the device #
list

After you've found it then select it

select #

Then make it pairable

pairable on

You can then scan for devices

scan on

You can then pair a device that it finds,

pair #

Alternatively now that you've made pairable you can now use the bluedevil-wizard to pair devices.

After you've paired and connected to the device you can go to the Sound Preferences control panel and select it. I have a set of Bose Bluetooth headphones and a Grace Digital bluetooth amplifier, I was able to play music though both of them using High Fidelity Playback (A2DP Sink) however the Headset Unit mode that's available for the Bose headphones doesn't work, this is probably the fault of Fedora 21.

1 out of 5 eggsDoesn't work with Fedora 21

Pros: None

Cons: I bought this because some reviews said that it worked on Ubuntu so I assumed it was Linux compatible, it's not, perhaps they changed the chipset and mine is different from the other reviewers. The Bluetooth Device Wizard on Fedora 21 doesn't detect it. I do see it on the USB bus but can't configure it,

Bus 004 Device 003: ID 0a5c:21e8 Broadcom Corp. BCM20702A0 Bluetooth 4.0

5 out of 5 eggsGBU521 Bluetooth Adapter

Pros: Needed Bluetooth for an older single 32 bit processor computer running XP.
Was easy to install, and works great.
