I bought this nail gun to use on a project I am doing at home. The nail gun often jams, it is heavy, and to get rid of the jam you need to dismantle the magazine unit, consisting of several screws and an angle adjuster. The assembly is tedious and time-consuming. Not for people with minimal mechanical skills. The last straw was that the piston assembly shifted and stopped working. Remember I kept the gun clean and oiled. I haven't filled a whole box of nails yet. The price was good, sometimes you get less than what you pay for. . .
