With all the ergonomics of the angle grinder, the lack of a lock on the power on is a drawback. It doesn’t work for a long time, the brush gets tired. Or did they come up with this on purpose? But it's all . But what is not garbage is that after 2 months I had to buy a gearbox housing. I don't even want to remember its cost. Jammed disk, tried to unscrew to change. I don’t know how it could be done, but when the spindle (on) was locked, a piece of the gearbox housing broke off. Such pies.
