The metal brushes are attached frayed and uneven. The plastic brushes are very crooked and not to use .. A few Korundstifte and diamond grinding points are not exactly in the center and thus run out of round and rotor grinding cylinders can only at very low speeds use, as they one else fly around the ears ,
Nevertheless, I give just 3 stars, because still some usable parts are still, which would probably cost many times together at the hardware store ..
Edit: After the metal brushes by now minimal, careful use all of the bristles break off and flew away and spread out across the room, I prefer still from a star.
