It isn't rich on features, but it gets the job done. If you're looking for a cheap recording device, this is fairly good for being only $30. It's not great as a system sound card, because it's pretty limited to the amount of work it can do, but if you need something to record with and already have a sound card, this should be great for you. If you're running Linux, it's supported in ALSA, but you don't have a lot you can do with it at a time. Overall it's good for what you're paying.
