Comment:This is my first impact wrench. I guess the biggest reason I picked this one is that you can buy parts for it. In this day and age, most things are like light bulbs - when they burn out, you just get a new one. If parts can be purchased, it must be durable. The price on this site was great.

Just simply can't be beat
Comment:I purchased my 231C in 1972 from my Snap-On rep who told me it was much better than his Snap-On model. This poor gun has been through the wars. Until 3 days ago, I have NEVER done anything to this gun but use an oiler with it. Not one single repair or adjustment. Finally, the trigger will not shut off the gun completely. My local IR Authorized repair facility said I could buy just the trigger parts, but I elected to go for the whole maintenance kit. Grand total - $30 + tax!! That's after 41 years of faithful service. I am buying a new one, too. After I rebuild this old one, I think I am going to give it a bit of a rest.

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.
