I bought this unit over 2 months ago. I could not get it to stay connected to my PC. After several attempts to configure it with the software, not only does it not play any sounds (other than the beeps when trying to set it up), but it won't even calibrate for the lights. I have been in contact with G.T. Power several times, and was told that the would ship a new card to me. But I still haven't received it. At this point I would not recommend this unit.
