Pretty decent drill/driver. Powerful and comfortable. The battery charges fairly quickly and holds a charge well. Power is regulated normally. The start is smooth, but you can see sparks in the engine vents at the start of rotation! Perhaps the brushes will rub in and will not be visible. In general, it does not irritate during operation, but suddenly!) It does not get very hot during prolonged use. Bits are quite normal for China! Not, of course, if you try to screw the Zubr self-tapping screws into concrete, you can throw out the bits. =) And for work at home, in the country - a very worthy option! And of course, it cannot be used as an impact drill! The blows are rather weak, and I'm afraid the body will not stand it. For these purposes, it is better to just buy a hammer drill! In general - a worthy option for home use! Solid four!
