BOSCH PKS 55 - not designed for long and hard work. This conclusion was made by me after purchasing this junk. The protective casing and the sole are made soundly - there are no questions about them, but the body of the electric motor, gearbox are made of plastic. So the bearings can heat up during operation and melt the mounting points, which will lead to jamming of the rotor and gearbox. In a word, the tool from the "green BOSCH" is just toys.
