Works great. I use it everyday in the body shop i work for. Much lower price than i had found anywhere else. These impacts usually last about 3 years when they are used every day several times as i do. It costs around 75 dollars in parts to overhaul the unit with a motor and brushes. If you cannot service yourself. I recommend just buying a new one.
