Thought long about this screwdriver from Makita buying as some competitive products also are good and cheaper! The quality of the electric screwdriver to remember is the same and has a lot of strength thanks to the battery. The batteries last full out to finish his construction projects without a break. The only thing is not as successful, is the Koffer.Zum storing enough but out! I've also bought the screwdriver and not the case !! I have the screwdriver also deliberately chosen without impact because the weight is to remember even if you work all day.
