I then tried installing the included software/drivers on the Vista machine thinking that the manufactures drivers might make a difference, but they did not. The software installer was slow, clunky, and took forever to complete after a few suspicious command prompts flashed across the screen. After realizing the software/drivers made no difference, I then tried uninstalling but the software would not uninstall - I ended having to use system restore to roll back to an earlier state to get rid of the software.
All-in-all, a bad experience. This item is already in the mail headed back to Amazon for a full refund.
Tried both drivers and they both failed. In the end they gave my computer the BSOD. I tried both adapters and both failed in multiple computers, returning this garbage back to whence it came.
Avoid this product and the seller!!
They do not even have a support page for driver download on their website.
This device had good range.
My bluetooth LE headset paired with it, and after working with windows settings, worked great.
bluetooth keyboard worked (Old one Bluetooth 1.0 or 2.0 or something)
Random Blue Screen of Death.
Newer Logitech BT4.0 mouse will not pair.
Random blue screens of death with watchdog timer in the message were appearing. I updated every driver on the computer and started uninstalling hardware I added in the last few months. The last thing I tried, and the only thing left that wasn't in the computer for years was this device. Once the CSR harmony radio drivers were uninstalled, my problems went away.
I looked on the web and found no later drivers. Neither windows update, nor device manager found anything newer.
It took over a month to figure this one out because the bluescreen provides no specific details and the only way to troubleshoot it is to start updating drivers and uninstalling hardware. Unable to return due to 30 day return warranty.
I recommend staying away from any CSR chipset USB adapter based on the failure of the logitech BT4.0 mouse to pair, and the BSOD problems.
If you purchase this device anyway, keep this review in mind if you see Windows Blue Screen problems.

I'm using them mainly for Bluetooth headsets. The sound (to me) is excellent. But then, I'm not an audiophile (can't distinguish the audiophile stuff). But to my ears, the music is clear, with good bass, treble, etc.. with no stutter.
NOTE: I did initially install the driver as directed in the after-purchase email. For Windows 10 users, this will NOT work. After a few back and forth emails with Costech tech support, the issue was solved by removing that driver. Their customer support was fantastic!
For eight bucks though, man it's hard to complain too much. Windows 10 installed the dongle with little hassle and I was able to easily connect my headphones.
