1 out of 5 eggsNot working

Pros: It's small

Cons: I have yet to get this to work. I've installed, uninstalled, and reinstalled drivers numerous times to no avail. It will not connect to my LG G2 or my Arriva Leo headphones.

Other Thoughts: I followed the instructions (no DVD drive on laptop, so I downloaded the Win7 x64 drivers from the website, started the install before plugging it in, then plugged it in when asked and finished the install. Then when I paired with the headphones, it installed more drivers. When I paired the phone...even more drivers. I did have some "didn't install issues" that supposedly you get rid of by making those be COM ports (via forums). When the initial install didn't work, I removed all drivers and tried again. This time for the phone/headphones I didn't let Windows install it, I pointed it to the install directory which really made no difference. I've searched forums to no avail. At this point I'm fed up. My phone and headphones worked find with my old laptop which had bluetooth built in. This new one needed an add on.

2 out of 5 eggsGreat Til It Died

Pros: Small, price, easy to set up.

Cons: It died after 41 days, disappointed. I guess what can you expect for the price. If i want Bluetooth, I'll replace my wifi card and get one with Bluetooth.

4 out of 5 eggsdongle-a-roo

Pros: It works, simply put. Windows 7 and Mavericks 10.9.4 compatible. Motorola buds($49) as a pairing match and a nexus 5.

Cons: Range is limited to around 30 feet but that is to be expected of bluetooth tech. Expect it!

1 out of 5 eggsIntermittent Range

Pros: Nothing

Cons: Kept connecting & disconnecting. Apparently a lot of people have had this issue. Got a GMYLE 4.0 USB adapter instead, it's been exponentially more reliable.

Manufacturer Response:

Thank you for choosing IOGEAR and we apologize for the inconvenience. The problem described could be related to your computer or diver sued. We recommend using the updated driver from IOGEAR.com for the GBU521. Again, thank you for choosing IOGEAR.

1 out of 5 eggsFollow Up

Pros: Compact
Cheap price

Cons: I'd tried it in my Sony Vaio Duo with Windows 8.1 and Sony Vaio regular laptop with Windows 7 to add external wireless mouse and this little POC do not work. I have followed the direction to download the latest driver since it is not a PnP. It took off the touch screen function in my Windows 8.1. Luckily, there was a discussion board I had found in the internet on how to get the function back. After uninstalling the software, I immediately use my unused Logitech Keyboard/Mouse and it was easy. It took me less than a minute to make it work versus downloading the driver and figuring it out why is it still not working. I'll try to return it to NewEgg if it is worth it. Very disappointed with Iogear. I thought highly of them but not anymore. It wasted my precious time and stirred up my sanity.

Manufacturer Response:

First, thank you for choosing IOGEAR and we apologize for your experience. As stated this is not a plug and play device. The software has been tested with and works with Windows 8.1. If you already have internal Bluetooth this device will not work. We will forward this to the product manager for review. Again, thank you for choosing IOGEAR.

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.
