I had the Expert briefly before returning it and the Ploopy Adept. The Expert doesn't have hardware remappable buttons, only software which IMO makes it no good. It is, IIRC a little bigger. The Adept does have QMK hardware remappable buttons, although mine had a button break and I never got it quite feeling right with the replacement case. I feel like they revised things from my early board and case and they didn't quite match up. I also think scrolling by holding down a button and moving the ball on the Adept is better than the Expert scroll wheel. Generally I like the feel of Ploopy's trackballs and that are Canadian but I do kinda wish they moved towards offering better non 3D printed cases as an option.
