    IOGEAR GBU521 Reviews

    Bluetooth 4.0 USB Micro Adapter is rated 4.3 out of 5 by 39.
    Rated 4 out of 5 by from Works great with OSX Needed this for a remote console setup involving two 27 monitors, and optical thunderbolt cable, and a Mac Pro. The thunderbolt monitors don't include a bluetooth radio, so I needed something else. This dongle uses a chipset (BCM20702A0) supported by the kexts that ship with Yosemite, so just works out of the box. Minor annoyance is that you have to reselect the controller on reboot (Using Bluetooth Explorer), but i'm sure this could be scripted, just hasn't got annoying enough yet to fix. Seems to work considerably better than the internal bluetooth radio when used with my Mac Book Pro. No Yosemite mouse lag.

    Rated 5 out of 5 by from Very Good Bletooth Device My laoptop was not Bluetoth enabled so I purchased thid device.It comes with the deice (tiny) installation disc and instructione. If you nhave Bletooth drivers in yor'puter that do not work, uninstall them befor running the new disk. Once mine was up and ruunning, I could easily pair it with my smartphone, speaker or any other Bluetoth enebled deice, providing I hsd the passwords. Mainly, I set up a playlist on my laptop, turn it on power saver or medium and put it and the attached USB Bluetooth in my baqckpack. Now I can comfortably walk down the street, subway or anywhere listening to my music on my speaker.

    Rated 1 out of 5 by from would not recommend to start, the plug is difficult to actually insert or remove. It is a super tight fit in all the USB ports i tried, and a couple times even required pliers to get a good enough grip to remove it. but that was the least of the issues. The main issue is that it was not at all reliable. It would drop the connection several times a day, sometimes requiring a system reboot in order to get it to work again, which can be difficult if your keyboard and mouse are bluetooth since you'll no longer be able to use them. I kept trying to get it to work properly for 2 weeks until eventually i gave up and asked B&H for a refund. Of course they happy to do so, which is why I love this shop.

    Rated 5 out of 5 by from Excellent little adapter...except This little product does exactly what it is described to do. However, if you also have a Logitech unifying USB adapter they may collide. My wireless trackball pointer goes totally berserk if both adapters are present and connected. Otherwise, it recognizes all my bluetooth devices including what I purchased it for, my Sony wireless headphones.

    Rated 5 out of 5 by from Perfect mate for a Mac Pro 5,1 (2010-2012) With a USB 3.0 PCIe card installed, we have horrendous Bluetooth interference and can't use BT mouse/keyboard when just a few feet away. With this little dongle connected to a monitor or a usb extension cable (anything that doesn't have your Mac Pro in between your BT devices and the dongle) we get great reception. Be sure to configure your Mac to use the dongle instead of the built-in bluetooth card:

    Rated 5 out of 5 by from Bluetooth 4.0 USB Micro Adapter by IOGEAR I am not a techie person. This is my first experience with using a dongle. Needed to purchase because it is the only way I can get my photos taken on my phone camera transferred to my computer. Plugged it into the hub I had just purchased and my computer recognized it. Followed the directions and I was able to transfer photos to my computer. I'm happy with it. Since this is the only item I've used it for I can't comment on the other uses. Please refer to manufacturer statement for other uses.

    Rated 5 out of 5 by from This thing really works In my office I am in charge of our music entertainment. I have a Bluetooth speaker that sets 20 or so feet from my desk. My main machine is a desktop system so it did not come with Bluetooth. This is the third Bluetooth adapter I have tried. The music would get choppy at times and break up if anyone walked between my computer and the speaker. With this IOGEAR adapter I have not even had so much as a hiccup through the speaker. This is hands down the best adapter I have used so far.

    my TV has a USB port, can I use this and stream to bluetooth headphones?
    Asked by: Alvin D.
    I have not tried, so I can't say for sure, but this dongle requires Bluetooth software on the device it is put into in order to run. I would have to say no, unfortunately.

    Have the Startech version, which works BUT after every restart have to turn off bluetooth, reinsert dongle then turn on bluetooth again. Using with mid 2010 Mac Pro running Sierra. Will the Iogear version stay connected after restarts?
