Cons:
Rotating knobs have a gritty feel to them, not very pleasant, had to change the top to some spare ones from a mixer I had.
If you play 2 neighbor pads simultaneously it doesn't work properly 2 out of 3 times.
The navigation is not that clear with OK, SELECT, etc, but you get the hang of it with ease.
Pros:
Great for the price, strong build and tons of memory.
30 editable sets which get you plenty of options live.
Easy to use, plug and play with a large library of sound.
4 external trigger possibility which gives you 13 pads to play in total, which is amazing for the price.
I definitely recommend it.
The only thing I couldn't find in the manual/box but was able to find in a video was the fact that you can only upload WAV files 48kHz and 16 bits.
