Effective, easy to use and clean. I bought it for spices (I often make Indian dishes) but it also works for grating cheese, for example. Be careful, I think there are three companies that have the same product, prefer the one that has a black addition inside the container because a new version has come out without the black addition and with slightly different blades that do not do the job properly according to reviews from abroad.
4 stars because it starts to smell and heat up after 30 seconds of use. I will add updates to the review after a few weeks of use because many times electric tools smell at the beginning and then "settle".
