«  The Swiss Army knife of the battery »

I use it for a little over a year. Chosen in store including the sensitivity and touch pads, very comfortable: we have (almost) like playing acoustic.
I used:
- As kit perceived as an adjunct to the acoustic
- As a trigger to initiate sequences on PC
- Like mini-kit apartment (with pad and pedal hihat kik) for training, oxen or schedule real-time realistic MIDI tracks

The pros:
- Stable, solid
- Built-in sounds very nice and varied (although it's not worth the best VST's time to record an acoustic drum track), multi-effects,
- Excellent touch and good sensitivity.
- Super 4 track looper built, great for improvisation,
- Easy to configure, customizable real-time controllers,
- Save settings on USB
- Many auxiliary inputs (pedals / pads) into a mini-kit.

The -:
- Not possible to integrate its own sounds or read an mp3 on for training (must connect an external drive)
- The implementation of the metronome only requires reading an empty track (!)

In short, it is mainly in the details view of many qualities. Worth every penny in retrospect.
