I use the coffee grinder to grind the seeds, oilseeds and sugar. It really works very well, the powder is fine very quickly. However, I feel that it heats up quickly. This may be normal. I have never had a coffee grinder before so I have no point of comparison. It does not take much space and is easy to store. It is however not very easy to clean in my opinion: the blades are not removed, so be careful. The key is that it reduces a very fine powder any oilseeds and grains, so I'm satisfied.
