I use it for on-stage finger-drumming. The visual feedback and customization of the knobs is phenomenal. It's a show all of it's own.
Build quality is very solid, buttons are durable and very satisfying to play.
Customizer software is very straightforward: a couple of setup options and some colors to assign to LED rings.
Not suitable to be played at night when other family members are asleep. The buttons are clicky.
The USB port looks solid, but strongly recommended to secure the USB cable to the body for live performances.
