Very disappointed in this device, after 3 uses 700 pulls the belt toward the piston broke on the right side, after negotiation, the unit has been changed. Again, after 5 uses this belt serious signs of weakness on the side droit.Il seem that there is a design defect, indeed the belt rubs on the side of the reel at what causes wear premature. So far I have not found a replacement part If the device meets my needs
