    I am homebound and mistakenly ordered an item from the seller for pick up. When I noticed my error, the seller went well beyond what anyone could expect and retrieve the item and then make sure she shipped it to me at her cost. Service above and beyond the call of duty for normal transactions. Not only is the item exactly or better than advertised, the shirt is also priced incredibly well. I would recommend and buy again from this seller anytime. Crofton,MD

    Just as advertised

    Works. Quick shipping. Just as advertised. I use it instead of a similar ASUS product that has driver issues on Linux and keeps disconnecting output devices. This one does the trick.

    Maybe fine, maybe not. It depends.

    It may work just fine for you. It didn't work for me with Windows 10. So I downloaded the CSR drivers and found the whole setup rather clunky. I did get it to work, but not always. I was using it for Bluetooth audio to a small amplifier. It sometimes would force the windows volume control up to 100 and try to keep going. I had to unplug it, then plug it back in, for that to stop. This is when coming out of Windows standby. Not easy to remove due to its tiny size. Depending on this that and the other, it might work fine for you. Didn't for my setup, so removed it to the drawer. I tried to see patterns for misbehavior and could not. Random failure due to the driver software, I think.

    Not up to task when using with Zwift on my PC

    This dongle was purchased soley for use with an indoor cycling app, and it proved not up to the task. So it is kind of useless to me. I will have to search for a better quality product. It wasn't inexpensive either.
