Works well, picks up dust very well. Bought as a replacement for the PC 505 I personally find the PC to be a bit better than the grinder but it doesn't have dust extraction so I think it's about the same overall I would recommend it. FOLLOWING I have two major complaints about this grinder. The front handle is too close to the bottom half of the grinder, unless of course the black and blue knuckles bother you. Second, it seems to have a mind of its own, if you want to grind in a circular motion it will want to go straight and vice versa. he also seems to jump a lot. However, when it works properly, it removes material very quickly, leaving a smooth finish. Before making a final decision to buy this product forever I would try it out or make sure there is a good return policy.
