great motor mount, everything is very good quality, bearings, plastic main gear, no slop in the pro shaft at all, only thing i don't like is the pinion gear has no grub screw, its the push on type, but the mount it self is definitely worth the pricequality is, the bearings are of good quality, and focus very hard
