I have several impacts, use 2 every day I am at work, an Ingersoll and a Chicago Pneumatic. Have had a half dozen of each over the years. I notice the guys in the shop gravitate to the Ingersoll brand. The new light weight with composite body models are scary strong. Some are approaching 600 ft. lbs of power, while the cheap ones barely manage 200 ft. lbs. They will twist the bolts for you.
