The deck powers on just fine. I put a tape in both slots to test, the tape 2 slot seems to work great, with all buttons functioning as far as I can tell. However the tape one slot didn't seem to do anything or play the tape when I pressed any of the buttons, not sure why this is, it could also just be user error as I have little knowledge on devices like this. All other features are untested and as such there is a chance they could be faulty, please keep that in mind when making your purchase as I can not offer a refund in the event any of those other features are faulty.
