The screwdriver would get full credit, if not its name would indicate a hammer action that de facto does not seem useful. I tried it in concrete. The result was not only mau, but virtually nonexistent.
Otherwise, the device is top! As a cordless screwdriver he does everything what is expected and the incredibly well. The settings (speed, forward, reverse operation, torque) work perfectly, the device fits comfortably in your hand and the battery has a high endurance. And even when the battery makes flabby times, the delivery as a quality replacement battery is yes. The whole in a sturdy suitcase and a gimmick nor a flashlight that fits in the spare battery and a belt loop (for me also irrelevant). The processing makes a stable and high-quality impression. I assume that I on the unit for a long time have fun. Strong buy recommendation.
