1 out of 5 eggsDied after 1 week

Pros: small profile and has a decent range.

Cons: As stated in the title, the adapter stopped working after one week of use. I tried it on different USB ports in my computer and even on other computers but it was just dead.

Other Thoughts: This adapter worked well but I was disappointed that it stopped working so soon, especially since it is priced at $25. I have recently purchased the ASUS USB-BT400, which has worked perfectly for at least two weeks now. So I would recommend that if are looking for a Bluetooth adapter, you should go with the ASUS.

Manufacturer Response:

First, thank you for choosing IOGEAR and we apologize for your experience. The product should not behave as you described. Since the unit is backed by IOGEAR's 3 year warranty feel free to contact our customer support at 1-866-946-4327 or email us: support@iogear.com. Again, thank you for choosing IOGEAR.

5 out of 5 eggsVery good Bluetooth Adapter

Pros: I needed this adapter in order to use a bluetooth keyboard for my PC, since I wanted more space on my desk's pullout tray (I have a Logitech G13 that takes up some space, but is well worth it).

This has a great connection strength, and I have never lost a connection, other than if there's other network bands interfering.

Cons: As I said, I have lost connection to the adapter, which causes my key presses to repeat, or lag.

I'm unsure at the moment if that was a software issue on my PC, or the adapter itself, however.

Other Thoughts: I can't give this an egg off even with the connection drops, since it's so uncommon to happen. It was a great purchase!

3 out of 5 eggsQuestionable

Pros: Works if you figure it out

Cons: Not plug-n-play

Other Thoughts: Took it straight out of the package and plugged it in. (Device driver not found) It's a install drivers first device which you have to download from the iogear website unless your computer accepts a mini cd. After you download, click the first setup icon you see in the first folder tree. If you go deeper into the folders and click a setup icon it doesn't work. Kind of a pita but I'm spoiled and used to plug-n-play...we are in 2014 right?? It works though but I was questioning it the whole time. Cheap enough I suppose. Does the job.

Manufacturer Response:

Thank you for choosing IOGEAR and we apologize for the inconvenience. The GBU521 is not a plug and play device, it requires drivers to be installed for your operating system. The updated drivers can be found at: http://www.iogear.com/support/dm/driver/GBU521#display. The instructions for the GBU521 clearly states the software must be installed before the GBU521 is connected to your computer. If you connect the GBU521 to your computer first Windows will load a generic driver that will not work correctly. Once again, thank you for choosing IOGEAR.

4 out of 5 eggsWorks, works well

Pros: Good working Bluetooth USB adapter.
no LEDs
small
simple driver software integrates with windows

Cons: hard to remove
not directly compatible with ps3 controllers unless you force install drivers which may cause some issues.
does not connect to wiimotes like my other dongle does in windows. It does connect to them on Linux though, so perhaps it's the driver

3 out of 5 eggs50/50 Chance of Device Being Detected

Pros: Very small, it works. It's plug and play with Mac.

Cons: Very hard to remove! I had to use tweezers to get it out.

Other Thoughts: I recommend buying this if you want to plug in this device in the long term. If not, then I don't recommend it.

Manufacturer Response:

Thank you for choosing IOGEAR. These comments will be forwarded to the product manager for review. Once again, thank you for choosing IOGEAR.

3 out of 5 eggs

Pros: Bluetooth 4.0
Small (also a con)
No issues with later versions of *Nix

Cons: Small

Other Thoughts: I list "small" as both a pro and con. It looks nice and does not take up much room, which is nice. However, it's kind of a pain to pull from some USB ports if you have big fingers .

Used mainly for my HTPC so I can connect a PS3 controller for some console style gaming accross the living room.

I also have an IOGEAR 2.0 bluetooth adapter that I bought a few years ago that is still working fine.

5 out of 5 eggsBest yet

Pros: Works well with Windows 7 x64. I had two other brands before that slowly melted and fell apart. This one has stayed cool. I've had it for seven months.I actually like the firm fit on my laptop so I won't lose it.

Cons: "Hey you with the WiFi smart phone. Just back away from my BT dongle and no one gets hurt." WiFi devices too close (less than 12 inches) to the dongle can lock it up. After moving them away, it usually self-restores in a few seconds. I also found that holding down a left mouse button too long on a web browser while scrolling down can lock it up, too. Not sure if it the MS mouse or not. Popping the dongle out and reinserting it restores it quickly though.

5 out of 5 eggsTwo years with no problems

Pros: Supports a lot of profiles. Small. Inexpensive. Works with my Nexus 5 & 7, headset, and mouse.

Cons: Tight fit in the USB port.

Other Thoughts: My wife and I both have one in our laptops and we've never had any problems. Get the drivers directly from Broadcom rather than the IOGear web site.
