Summary: The expected DeWalt quality just isn't there. Starts slowly and takes it several seconds to get up to speed. Grinding wheels are out of balance. Had to add shims to each wheel to get it to run without it "dancing" off my work bench. I have a 40 year old 8" Sears grinder that is far and away a better grinder. It hits its top RPM almost instantly, and has much more power. It also runs much, much smoother.
