This is related to the operation time, however, in the instructions, and that I could deal with the water because I've looked at before buying the reviews here, and my cover therefore never came into contact with water. I take out easily for cleaning a brush, and, strictly speaking, do not have to clean the great cover, because if some dust off the sticks milling, the brush does not drive - so then it's just like that. Therefore, is not equal to an epidemic.
The criticism that the lid would be to sit up only with much fumbling and close, I can not understand at all. This is then probably the fact that the user is a Grobmotoriker. The lid is clearly marked, the mark does not disappear, and you could tell from her pure feeling, when the cover is properly seated. Because I had really never been the slightest problem.
That you should not grind oily foods such as nuts or very hard foods, is also in the manual - so who complained that the mill glued or stops, is also to blame.
I grind with the mill primarily flaxseed and oatmeal. Since flaxseed are also oily, you have to bring the whole thing afterwards with a teaspoon from the mill. Since then, I always grind a tablespoon of oatmeal with flax seeds, the result falls almost automatically from the mill, because the oats absorb the oil and clean the mill during the grinding it were equal.
You have to remember that it is a small mill with a weak engine plane. Of course, it takes it a foul if you order full glass pot 3 minutes continuously grinds rock-hard coffee beans. Here, however, it also lacks the basic technical understanding of some people.
CONCLUSION:
Yes, the mill has a few drawbacks, especially that with the water in the lid should not be - fortunately, I was forewarned by the reviews here. But all in all the price / performance ratio.
