4 out of 5 eggsNow works fine.

Pros: Software and set-up was easy and it worked pretty easily.

Cons: Sound over headphones low is bandwidth. I guess this thing does not implement "A2DP" - the 'HiFi' Bluetooth interface.

See below: Updated driver fixes low BW Audio.

Other Thoughts: I wanted this for HiFi bluetooth music listening, but this doesn't work for that. Oh well - I'm only out $8 and I can probably use this for other things...

Update: Latest Drivers (Version 6.5.1.6000) fixed problem. Enclosed drivers not so good.

1 out of 5 eggsEasy setup and use. When will there be Windows 10 support?

Pros: -Easy to setup software included
-Great product design with one time plug-in in mind

Cons: -Connection to my audio headset does not work well (i.e. drops connection, low-quality audio output, inconsistent with my headset)
-Windows 10 support is not available yet

Other Thoughts: I would easily give this product a better review if there was Windows 10 support available.

4 out of 5 eggsWorks very well, but if less than 10-15 ft. away

Pros: Works very well and connects successfully and very consistently.

Cons: Will not communicate well when further than 10-15 feet away. I have this in a front-usb port to make the airwaves clear and direct, but have to sit at the closer couch to get my keyboard/mouse combo to work. My other computer with bluetooth built in can communicate with the same setup for about 30ft.

5 out of 5 eggsGreat product!

Pros: Works with PS3 Controllers!
Works with Multiple PS3 Controllers!
Works.

Cons: None that i know of, had to install a Bluetooth driver, from SCP, to the dongle itself to make it work with PS3 controllers, but that is it!

Other Thoughts: Install dongle software/driver from cd first, then, to work with PS3 Controllers, go download SCPToolkit/SCP DS3 Drivers. Use this program called zadig.exe in the folder zadig to install bluetooth driver to dongle(warning will make dongle only work with PS3 controllers, unless you can get the old bluetooth driver onto the dongle again). Then just install the SCP software/driver, hook controller up with usb cable, then unhook and you are good to go!

Will not work with fake PS3 controllers, like the one i got off newegg :-/

3 out of 5 eggsGood Range, Needs clean reinstall of Windows 10

Pros: - The range is good, flawless operation when I finally reinstalled Windows 10.
- Small

Cons: - Blue screens when I upgraded from Windows 8.1 to 10
- Fixed this problem by reinstalling Windows 10 from scratch.
- Had to use an extension cable for better reception.

Other Thoughts: - For better results, use a USB extension cable to relocate the main unit away from the CPU case.
- Before reinstalling Windows 10, my computer instantly blue screens whenever I turn on a previously paired headphones.
- For those worried about the Windows 10 license, your upgrade license carries over when installing from scratch.

1 out of 5 eggsBlue screen of death Win10

Pros: Nice hardware, but no Win10 drivers. Strangely, works perfectly with Ubuntu 14.04.

Cons: Asus does not have a Win10 driver for this bluetooth adapter.
When I try to link my Note4 phone with the BT400, it gives a blue screen with error "Kernel Auto Boost Lock Acquisition", then the PC shuts down. This is a brand new PC, Asus GR8. It works perfectly with Ubuntu 14.04 - no driver installations required.

Other Thoughts: I don't want a case number, ASUS just release updated drivers for Win10!!!!!!!!!!

Manufacturer Response:
