I have many quality tools, from Cornwell to Craftsman, even some goodies from Harbor Freight. You can tell a decent tool by the build, the feel of the bearings, and the "play" in the tool. This one feels pretty good to me. It works great on my supercharger, but I use a fairly decent sized stand-up Craftsman that gives pretty good flow, so I can't comment on how it would perform on a smaller "pancake" compressor, but it doesn't. It seems to me that it is particularly lacking in air, no more than most of my other pneumatic tools. I like its short stroke, it should be less than 1/4 inch, buffing or lacquer cutting. The parts stores should have one of these in their kit and some 1000/1500/2000 pads for it. It comes with a very good buffing range and buffing pads of different densities. which appear green, orange, yellow, blue, red, from hardest to softest. It certainly feels, durometer is one of the few tools I don't have "finish polish" It also comes with multiple grinding wheels and different sizes of grinding wheels, but not in grit as they are all 120 grit to have. Good for basic sanding, but not great for buffing paint tips. Comes with a nice standard air connector and a needle to insert into the tool to lock it in place while you change backs (available in 3 sizes). This is a very complete kit pick. Polishing headlights costs between $25 and $35 at most stores. If you make 2 sets of headlights, you paid for this tool. This is not a problem. I'm glad I have it, it's big with a nice short stroke that makes it easy to steer and maneuver safely. And it comes with a lot of accessories. I recommend it.
