Rated 2.0 out of 5 by 1 reviewer.
Rated 2.0 out of 5.0 by Great Tool, Shabby Auto Buffer I purchased this tool because I wanted a powerful, cordless option for auto detailing, and it would be compatible with the other Milwaukee M12 tools in my toolbox. I really wanted to like this thing. It is sturdy, powerful, and feels great in-hand. Unfortunately, the wooly 2" buffing accessory is complete garbage. The attachment started shedding fibers immediately, even with a light touch. I hand washed it to shake out the worst of the loose fibers. I even vacuumed it with an upholstery brush. No dice. After I took it for its first buffing run, it looked like a white mouse had exploded on the hood of my car. Cleaning up after the tool far outweighed the time it should have saved me. This is undoubtedly a great tool for grinding, polishing, and sanding. However if, like me, you are just looking for something compact and powerful to help take wax off your car, this is probably not right choice. At least not until Milwaukee or a third party puts better quality accessories out there. Or unless you're really into a ride covered with white polyester fuzz. May 18, 2015
