later The dust collector is not very big, falls off with use. Even when connected to a vacuum, it ejects more dust than other brands I've used. But this one was at a great price. It works well and if you are on a budget this is the grinder for you. Annual update: DO NOT buy broken! I've never used it for serious grinding, but it broke after a year of use. It just spins at a very high speed, but it doesn't have enough power to spin when pressure is applied to it. If you try to grind something, it just sits there with a buzzing noise. This also happened (of course) a month after the factory warranty expired. If you buy this make sure you get the extended warranty if it has one. Or better yet, buy the best brand.
