Received this as a gift as the buyer knows my extreme passion (obsession?) for keeping my car in tip-top shape. Therefore, it is used for buffing/polishing small areas of the car that are difficult to reach with a 5" or 6" pad (A/B pillars, etc.). I only hooked up my air hose for a quick test and am very impressed so far. Long term use will determine my final rating but so far so good.
