If ne short review: A workhorse that is easy and powerful. That's how it should be. So far I have not had screw, which could not be turned in or out. And that even in reinforced concrete. The fine adjustment of the speed is wonderful. Level 1: slowly and powerfully, Stage 2: fast and not quite powerfully. The battery lasts a long time - a very long time. The percussive function now is not the hit, but in brick always sufficient. Oh yes, the chuck is also very stable and the drill or bits are very well recorded. I would buy like to have a second ;-)
