GOOD: Sound is OK and it has MIDI.
BAD: Very difficult to setup, not stable, user instructions are garbage and site don't have videos to show exactly how to set up, wher to place the camera, how far, how high, the angle of camera etc.
Excellent drum replacement if you need to practice
Don't replace the feeling of a real drum, but at least sounds pretty good. I had some is issues with the set up, it's quite difficult at first but once you are in a good placement and a correct distance is much more easy to play
