5 out of 5 eggsBest little bluetooth dongle I've used

Pros: Best little bluetooth dongle i have used. Just works no issues. If i recall its been some time, its super easy just use the disk it comes work and works like a champ, my mouse works perfect no drops or anything.

Makes it easy to add bluetooth to desktops or laptops without them.

Also a bonus if you plan to build hackintosh's this is the way to go, just get the right kext which you can easily google for, run the kext installer and bam.. works perfect with apples magic mouse, or my razer orochi mouse for that matter.

Cons: Only con i could see is if you don't have a usb extension cable which is dirt cheap, you may have issues with it being small when used with a desktop. like being able to quickly loose it or hard to remove i guess, but those are minor issues.

Other Thoughts: If you need bluetooth and have a desktop and a free usb slot, get an extension cable and you will be rocking the best bluetooth device for the price. or any needs for bluetooth, hackintosh./laptop without one

2 out of 5 eggsWorks, technically

Pros: -Is a working blue tooth adapter
-cheap, small
-not much else

Cons: -Does not support aptX
-slow speeds
-drivers were not easy to setup

Other Thoughts: So, long story short, I ordered a bluetooth pair of earbuds and this bluetooth adapter to go with my phone (galaxy S4) to try out all this new-fangled wireless stuff (wireless charging is pretty sick).

I got my earbuds today, they are a mid-range set. I have a pair of cheap wired earbuds (3.5mm) which to me sound fine. I was *floored* at how bad the sound on these were when paired with my computer to the point I was going to send the earbuds back. I was ready to write off bluetooth as worthless entirely.

I decided to read through the manual and saw a little blurb about aptX and decided to try them with my phone (which has aptX) just for curiosity's sake. It sounds fine. Good even. Point is, if you are planning to play any sort of audio over bluetooth... this adapater is not for you.

Additionally, my transfer speeds between this and my phone are like, 70kb/s with the phone right next to the adapter. That is far too slow, so I got an app to run an ftp sever (phone and computer on the same home network) which goes much, much faster.

Should also note, the driver setup was pretty terrible. Including one 'supported' function that just... doesn't have a windows 7 driver (I manually installed the 'generic unsupported bluetooth function' driver).

So, all in all, this adapter failed to deliver usable quality/speed for the two things I bought it for, although they technically worked.

Manufacturer Response:

Thank you for choosing IOGEAR and we apologize for the inconvenience. The speed of the GBU521 is dependent on the device connected. Most cell phones and providers have limitations when using a bluetooth connection. The GBU521 is not a plug and play device. If the instruction s in the manual are followed installation is step by step. If the GBU521 is connected before the software is installed, generic Windows drivers will load and cause a conflict with the GBU521. The GBU521 does not support APTX audio however this will be forwarded to the product manager. 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. for the problem of poor audio. The GBU521 carries a 3 year warranty. The GBU521 is fully compatible with Windows 7. IOGEAR suggest downloading the upgraded driver from the support site instead of using the included CD. Once again, thank you for choosing IOGEAR.

5 out of 5 eggsWorks as expected

Pros: It connects to anything blue tooth I have: phones, head sets and blue tooth speakers. All my BT are ver 3 and up. Range is 30 ft if unobstructed, walls and wall corners shortened it of course.

Cons: Remember the spec is 3 mb per sec. Do not expect your full 32 gb of video and pictures from your phone to move as fast as your direct usb connection using a cable.

Other Thoughts: Now has drives for up to Windows 8.1 64 bit available.

1 out of 5 eggsIOGEAR USB BLUETOOTH ADAPTER

Pros: It worked for a while with my Creative T12 Bluetooth stereo speakers then quit. I have tried reinstalling the software two times to no avail. And yes, the speakers are good, very good for their size. They work great with my phone.

Cons: THE QUIT WORKING AFTER A FEW DAYS.

Other Thoughts: It's a hassle to get help from the mfr. I may just throw them out and get another brand.

Manufacturer Response:

Thank you for choosing IOGEAR and we apologize for the inconvenience. The GBU521 is backed by a 3 year warranty.

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.

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.
