I bought this so I could use my PC as a recording studio. Out of the box, it worked well but when I downloaded the official drivers it became very flakey - every few minutes it would die and I'd have to unplug it and plug it in again to get it back. Deleting the drivers lost the ASIO capability, but at least it works reliably. The drivers referred to 4 inputs (1/2, 3/4) but, in fact, it has two inputs - there is another pair on the back, but they are accessed with a push button. Unfortunately, that's also on the back so it's quite awkward to switch over to using the rear inputs. Sound quality is really good - big step up over the PC's built in sound card.
