This is an excellent tool. Superb Battery life, 3 speed setting is an excellent feature for various types of fasteners. As mentioned before, the battery life is phenomenal. This morning on a fully charged 2ah battery I drove about 500 screws and the battery still has about 2 thirds of charge left. Superb tool.
