The unit is super: Low weight through the small battery, yet a high torque. No memory effect and no self-discharge of the battery (in my previous cordless screwdrivers, the battery was often through self-discharge after a short working time empty / Who thinks of the regular recharging). The built-in work light is handy. With the cordless screwdriver and screws can be solved, which are secure. One battery charge is enough for several screws (screw diameter 6 mm). The chuck into place audibly. Some getting used to are the visible charging contacts on the battery. Charging and recharging works fine.
