Working properly but rarely sometimes it stop,but never bother me!Very powerful tool and the battery it holding power for long time!It with ATC feature! It a heavy-duty rotary combi-hammer. Instead of a "stop safe twisted handle," it features Active Torque Control (ATC)—a safety clutch system that instantly stops the motor if the drill bit binds, preventing the body of the tool from spinning uncontrollably and twisting your wrists. No charger Battery 5.2 ah
