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,

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.

Cons: none

Other Thoughts: I bought this for my computer challenged Brother. He can even use it, I did have to install it for him.

1 out of 5 eggsDo Not Buy

Pros: None

Cons: This device does not work reliably whatsoever. I spend more time trying to connect my devices than actually using them, and sometimes it simply refuses to work. It also prevents my computer from restarting properly, because it is somehow seen as a bootable device. Do not buy. For all I know it comes with malware on it.

4 out of 5 eggsIt works

Pros: I use it to tether my bluetooth controllers, like PS3, PS4, and Wii, to my PC.

Cons: It's a real pain in the fanny to remove, since there's virtually no grip on the thing. I usually have to remove it with pliers.

2 out of 5 eggsNot my fav experience

Pros: Exceeded my expectation for it's price while it worked.

Cons: Stopped working in under a month. Voices went robotic, then silence. I have never had a device meltdown mid-use like that. I had a laptop with Bluetooth, so switched back to that. IOGEAR has a phone only remediation system that I am less than pleased with. can't wait to fight with their warranty system on the phone.

1 out of 5 eggsNo range and a 5 second delay

Pros: It connects and works well within range.

Cons: The range of my device was about 5-6 feet. Any sort of obstacle at all completely interrupted the signal. Once signal was lost, moving back into range left me with a 3 second delay in the sound. I am not satisfied with this product and will be returning it.

5 out of 5 eggsEasy to install, worked perfectly

Pros: Just plugged it in, no need for the software that came with it to be installed. Paired up with both the KB and Mouse quickly.

Cons: I really didn't find any cons.

Other Thoughts: Great product for the price, worked well for my needs. I didn't need to worry about the range as the KB and Mouse will remain on a desk. So, I can not comment about the range.
