Remarkably cheap for what it does. For some reason my on-board audio ceased to work on my general purpose machine (I have another machine which is dedicated to audio but it's useful to be able to play stuff on the machine connected to the net) and I bought this device as a quick fix.
Delivery (to Spain) was good and it turned up within a week, The unit is solidly built for the money, but I have to agree with most of the other reviewers, the 'support' is appalling. No instructions of any sort and the CD gives no indication of which (of several) drivers to install. That's why I give it 3 stars, otherwise it deserves at least a 4, if only on a price vs spec basis.
For anyone still struggling, the drivers you want are in the directory CM6206(XP,VISTA,WIN7), go there and then select your OS (I'm running XP) and then double click on 'install.exe' - and all should be good. You do need to reboot the computer after installation.
FWIW, when I plugged the unit in, Windows rushed off and automatically installed a set of Windows generic drivers - and they did work. However, although I didn't explore it further, I suspect they won't allow access to all the features.
