It looks professional out of the box, but I am totally disappointed with its playability and functioning. I didn't expect it to be this bad, I guess it varies from product to product.
1. The pad sensitivity is different on each pad. Thus, Its likely that you will miss a hit. Velocity is terrible and the pads are too stiff.
2. The pads bounce and over trigger notes. I tried recording a drum beat and later I figured that there are lots of unnecessary notes on the midi line, that I didn't intended to play. Eventually, I figured that, sometimes pads trigger the same note multiple times.
3. Sometimes hitting one pad triggers the others around it. For example, when I hit the kick pad, that also triggers the snare and hi-hat.
