Review: Nice cordless polisher for the house - I grabbed this Dewalt polisher for weekend projects and to clean up our family SUV in the driveway. Cordless is huge, no dragging cords around the kids bikes. Good power and i can dial the speed down when my son helped on the hood. Battery life’s decent and the handle feels sturdy. Review: Beast! Great product! So reliable. - What a great product. Makes my marble so shine. The device is lightweight but have a lot of power. I have the 6.0AH 20V XR battery.
