For this heavy Chrütermühli made of high quality stainless steel, the manufacturer gives a lifetime warranty (except for the sieve). The sharp diamond-cut grinding teeth crush even firmer material in no time at all. The magnetic holder holds the grinder of the mill firmly together, a sliding ring made of nylon facilitates the back and forth rotation. Another plus is the ease of cleaning in the dishwasher. Do not bring the sieve into contact with rusted parts and do not leave it in sharp cleaning agents or alcohol for a long time.
