I hated it because the software was shit. I only used it in rentals, so additional shenanigans were probably going on, but what I remember:

- on home screen icons for functionality would never stay in the same place. They were shuffled based on "recency"

- in some menus you could only scroll to the very top and to the very bottom, in others the scrolling would wrap around

- in some menus you went further down by shifting the knob right, in some by clicking

And other minor and not so minor annoyances
