In general, I would say, that it is a very good technical solution that allows a user avoid loads of cables and power. I use it with Kemper set for effect when the pedal has the motion.
Issues I have met (and understood the core): after some time of use, the screw that controls the motion stiffness goes lose, and in loud environments (live concerts or even rehearsals) the pedal thinks it is a motion and does not stop the effect - so you have a wah sound even when you are not touching the pedal. It gets fixed by screwing that bolt from time to time.
I would note that it is very diverse, since you can adjust sound by the Kemper settings. However, I still lean towards analogue solutions - they sound tad better to me.
