Used Acus M1 with M1 Plus Heavy Grip. Used and still in great condition. Comes with traveling case, standard 3.0mm, 3.7mm, and 4.5mm strokes, housing tool, wrench for adjusting stroke, extra O-rings, standard lightweight M1 Plus Grip, two 3.7V/ 7.40Wh batteries and battery charger. Also threw in additional never used 4.1 Heavy stroke. Never had any issues with this machine, just parting ways with it as I need to invest in other shop materials.
