So far, so good
Comment:I bought this to replace junk from HD & Lowes. It will get light use at home, but at least has parts & support available. The instructions stress lubrication, but are vague about how to add grease and what to use. I had to buy the IR lubrication kit to find out.

Best impact wrench I have owned
Comment:I use my impact wrench for changing tires at home. This wrench is much smoother than the comparable wrench from Harbor Freight that I had for five years. I would definitely recommend this to anyone especially for the price at Factory Authorized Outlet.
