I have been working with this grinder for over a year. The main drawback, which nullifies all possible advantages, is disgusting dust protection. After a fairly short work, the start button shows off: all sorts of rubbish is instantly stuffed under it, and in such a way that you have to pull the plug out of the socket. Naturally, no one considers the repair of a button to be a warranty and it is cheaper to spit on the warranty and repair it yourself. Brushes wear out with terrible force - well, brushes cannot be worked out in six months, but it turns out it happens. Since he spat on the guarantee, he climbed inside to see what was there and how. I was extremely surprised by the almost dry gears and the fact that there is no stator mount. This is generally nonsense. The tool is cheap, despite the decent cost.
