Good design, easy to use. If not for the shoals, it would be possible to recommend for purchase. Impact mode tends to turn off. Sometimes. This is especially effective during drilling. The move stops, you push harder, but she still doesn’t go any further. And only when smoke comes out of the hole, you stupidly understand that you are just heating the drill. At the same time, to drill concrete, there is not enough power, but to grind the lining, it is quite enough. It gets very hot when used for a long time. The metal case of the gearbox actively removes heat, but no less actively overheats the lubricant. Once a quarter I open it, I make a revision, I add lubrication.
