I've owned the kit a few years but have only been able to play it 2 periods of a few months. I would say at absolute most, I have played the set 40 or so times for 15m-40m each time.
I haven't messed around with the drum module at all, so it's in really good shape.
Pads are certainly in good condition as well, might be missing a screw and washer or two that were misplaced, but thats easily fixed. I was considering getting a double bass pedal for it, but the room I have the drums setup in isn't very flat, and I haven't felt comfortable on it since moving here. Just thinking some one one else should enjoy it.
