The hammer/drill switch stopped working properly after 2 weeks. There was initially some kind of weak click, and then the fixation disappeared altogether. Repaired. The reverse is fixed poorly, the button pops up all the time, you have to press it constantly during operation. A serious backlash, up to the point that the holes are a little larger in diameter, you can, of course, take this into account and take less drills, but this is some kind of nonsense. The cartridge does not hold the snap well. Two or three holes and you have to clamp the drill with a new one. Morochno. Not worth your money at all.
