I have not been using it for a long time, I understand that this is a professional Bosch. But under normal use it will last a long time, I like it as a minimal tool . Under 6 and 8 collets there are all cutters for a furniture maker . I considered the same model only 1200 watts (6-7 tons), it is cheaper, but such a tool must be stored in a separate case, but that one did not have this one. Just salvation, with a case and with different collets and more powerful. In short, I'm happy. Frazier has already beaten himself off
