A good model, but she can not cope with the walls. Took to drill the walls. Completely disappointed. Moreover, after all, I chose according to the characteristics, drilling of concrete was promised. Pobedit drills - they took everything from the old DWT. With this one, 10-15 millimeters are drilled, and that's it. Specialists said that concrete is different. Why didn't they say this before. But in the end I have not the cheapest, but completely unnecessary drill.
