The main reason is the poor concentricity of the drill chuck. For screws which is still in order, but to drill it wobbles too much. However, it is still significantly better than in the last comparable Metabo machine that I had in my hands.
The build quality I find decent but not top notch. With less should not be satisfied as a handyman. In this respect, I doubt that the machine meets the demands of professional users.
Furthermore, I also regret that the times in which the Bosch machines - the Greens - came exclusively from Germany and Switzerland, are over.
Annoying I also find the registration in order to obtain the three-year warranty. The fact you have for each battery, the charger and make the machine individually. Why not simply gives Bosch 3 year warranty - ready?
