I am a perfectionist and have hours compared until I came to the conclusion to this new model of the house master. And what should I say? Price Leistungsverhältns absolutely top. On the Li-ion technology nothing more passes and the technology connected with expediency from the house masters come together in this product. Sorry, but who needs the obsolete technology from Bosch, the acts with adapters. In my opinion, this is the battery screwdrivers for household use, although I do not so much stand on white, but that's a matter of taste. The only criticism is the charging time for the battery. This is, unfortunately, at the cost charger and results in complete evacuation to a charging time of 4 hours. As I said for household ok because after 14 days still have the full power available.
