I wanted a mill to grind flax seeds very finely. I got chi ... for years with a blender in a jar (a trick I had tinkered myself) ... I put 10 minutes to grind a handful of seeds. So I ended up buying the mill was highly rated in Amazon comments for precisely flaxseed. And then: a miracle! This mill are completely magical: in 10 seconds it grinds impeccably and finely a good amount of flaxseed. I am delighted with this device!
