I've been using this for more than a year. You can use it to attach a record player/cassette deck to your pc if you want to digitise your music collection but I use it to connect (music) keyboard for music-making and it works flawlessly for this. There is only one input, plus one for a (specific type of) microphone so if you want to record more than one instrument at a time, you'll probably want to go for an interface with more inputs (obviously, you're going to pay more for that). If you are just starting out using your pc to make music, bear in mind that you'll probably need a MIDI interface as well (for about the same price as this). Incidentally, I don't know why they are saying "NEW" in the product heading - this has been in production for well over a year.
