A 1a product of Metabo! Even during the assembly of a carport with different sized screws and many angles made me this Schraubet not abandon! For the small size, a "strong" companion! The battery lasts a long time and if it is something weak in the breeding, purely in the charging station, a short coffee wads and even the battery is full again and it can go on. The supplied bits and the practical carrying case to keep everything together clean and orderly. So make DIY fun
