The IOGEAR Bluetooth USB Micro Adapter offers Bluetooth connectivity at a fraction of the size of normal Bluetooth USB adapters. About the size of an adult fingernail, the IOGEAR Bluetooth USB Micro Adapter allows users to connect to all the latest Bluetooth devices like cell phones, PDAs, mice and keyboards. Because the Micro Adapter is so small you can easily plug it into your computer without blocking any surrounding USB ports. The Micro Adapter also features Bluetooth EDR (Enhanced Data Rate) technology for transfer rates that are 3 times faster than traditional Bluetooth 1.1 and 1.2 adapters.

The Micro Adapter allows users to connect up to seven Bluetooth devices together and transfer even the largest files quickly and easily. With the Micro Adapter's lower power consumption, you can enjoy longer battery life on your notebook computer. This Bluetooth Class 2 adapter is compatible with both Mac and PC computers, and offers a wireless range of 30 feet (10 meter). It is great for both home and mobile networking needs.

5 out of 5 eggsPerfect size !!

This review is from: IOGEAR GBU421 USB Bluetooth 2.1 USB Micro Adapter

Pros: This little Bluetooth dongle is perfect in size to completely forget that it even connected. It was extremely easy to set up and so far is working perfectly. I have two desktop computers ( one is mine and one is wife's) and a laptop. Now all three can communicate through the Bluetooth connections with each other as far as sharing pics, documents, etc. and I don't even see the little unit (it's in the back of the desktops of course) and takes up virtually no space.

Cons: So far none - IOGEAR has worked great for me for several years so far.

Other Thoughts: The other Bluetooth dongle that I have is a few years old and still works great but is over three times the size (length) of this new one. If this keeps up we'll have complete computers the size of a credit card and can be carried in a pocket easily !!!!

1 out of 5 eggsDoes not last

This review is from: IOGEAR GBU421 USB Bluetooth 2.1 USB Micro Adapter

Cons: This is the second one of these I have had for my lap top. They last a couple of months and without any known cause they just die.

Other Thoughts: I would not recommend this product.

3 out of 5 eggsHassle at times

This review is from: IOGEAR GBU421 USB Bluetooth 2.1 USB Micro Adapter

Pros: Great price, easy to install

Cons: I've noticed that it tends to disconnect a few times a week. This becomes quite annoying and I have reinstalled the drivers on win 7 from their website and the problem persisted. It's come down to the point where if disconnects I just unplug and replug the adapter. Happens maybe three times a week.

1 out of 5 eggsCompletely Useless

5 out of 5 eggsGreat adapter with support for (PS3 bluetooth software)

This review is from: IOGEAR GBU421 USB Bluetooth 2.1 USB Micro Adapter

Pros: - Cheap
- 2.1 + EDR
- Range is as good if not better than the 4.0 version.
- Light to indicate connection/activity

Cons: - Wasn't free

Other Thoughts: This was my third and final attempt at getting a Bluetooth adapter that works with the PS3 controller software (the first one was an Iogear 4.0, second was an ASUS 2.1+EDR but it doesn't work in current version of the software, and this one took a few tries to get the drivers right but now it works like a charm!

2 out of 5 eggsNeed help configuring

This review is from: IOGEAR GBU421 USB Bluetooth 2.1 USB Micro Adapter

Pros: unpacked it and instructoins seemed easy so far

Cons: It tells me to double click on the bluetooth icon on the bottom right, but it doesn't seem to be working properly

Other Thoughts: Currently im trying to get my computer paired with my Onkyo surroung sound stereo receiver which can pair with devices through bluetooth.

I have done this with the receiver using my phone no problem. But with the computer i am confused on how to do this or if its possible. With the reciever i hold down the the bluetooth button and thats when its time for a bluetoothe enabled device to start searching for the receiver and pair with it.

So with this device how do i 'search for devices'. Im trying to play music from my pc to my receiver if this is possible.

1 out of 5 eggsDon't buy for Windows 8

This review is from: IOGEAR GBU421 USB Bluetooth 2.1 USB Micro Adapter

Pros: Small, Worked fine on vista/7

Cons: Can't get it to work on Win8

Other Thoughts: IOGEAR's "support" in getting it to work with Win8 was pathetic. They had nothing to say to me other than, "the driver has been tested with windows 8". As if that invalidates the fact that it is CURRENTLY NOT WORKING. They made no attempt to help me troubleshoot.

Manufacturer Response:

Thank you for choosing IOGEAR and we apologize for the inconvenience. The Windows 8 driver for the GBU421 has been tested with Windows 8 32 bit and 64 bit computers here at IOGEAR and we have had customers use this same driver on Windows 8 systems in the field downloaded from our website. The Driver was downloaded again today and installed on a desktop computer with Windows 8. There were no problems with the software installation or operation of the GBU421 under Windows 8. Since the GBU421 is working on your Vista and Windows 7 computer the GBU421 is working. If you send an email to support@iogear.com and request it go to a product manager they will review your setup. Please be as detailed as possible. Once again, thank you for choosing IOGEAR.

3 out of 5 eggsEasy to set up, but frustrating to use

This review is from: IOGEAR GBU421 USB Bluetooth 2.1 USB Micro Adapter

Pros: It is very easy to set up with its plug and play nature.

Cons: It won't allow the computer to go into sleep mode; you have to unplug it anytime you want to. It will occasionally drop the device it is paired with. ( Happens weekly with my Turtle Beach headset )
