A drawback in my opinion is that the device should be easy and too slippery. When working with the pads, to do this mostly with a lot of momentum and since the part wobbles but still too much on the table around, but this is certainly also due to the size. The sensitivity of the pads do not like it so much. When pressed, it does not address real and which then leads back to Problem 1. This can not resolve by the software. The LEDs in the pads are quite nice but unnecessary, the money could also have been investing more meaningful. Nevertheless, I would say that the pads are a lot better than the botched things in Akai MPK-25 (Perhaps the problem because now also fixed, but in my keyboard are terrible). The pots here are neat and slide smoothly but with a "valued" resistance. Overall, the part OK but who has the money and the place had better get something thicker.
