It doesn't seem to bug me.
Actually, I really don't play MM anyways. I had wanted the trackballs for bowling games, golf games, centipede/millipede, crystal castles, shuffleboard, & horseshoes.
There's about 2 1/2" clearance on each side of the ball, for those games, it feels pretty comfortable to me. The panel does look kinda tight, but I've got it set up to be just right. You're not fumbling over the other controls. It was tricky placing the spinner so it wasn't a spot where it would be in the way with the buttons.
