Similar to the previous writers, the situation is as follows: when drilling wood panels and boards, there were no problems. In brick walls, it is also quite tolerable to make holes of 8-12 mm for dowels. Noisy but goes slowly. If you need bigger holes in the brick, this is where the whole thing begins: the blow is weak, the drills scroll in the cartridge, there is wild heating. It takes as much as 2-3 minutes to drill, or rather dig a hole of 16-20 mm. After a couple of months of such a dance with a tambourine, a backlash appeared in the cartridge. Some inconvenience, although when buying I had hopes for this seemingly serious brand.
