I went from pre-ground coffee, to an electric blade grinder, to the MK4, and it’s worth every penny. The only problem I had was deciding on a color. :) After reading a review in New York Magazine, I knew I had to have one. Plus, they included a link to Loewen META, which shipped the grinder much faster than expected and packed very well. I’d highly recommend you do business with this company. As for Comandante, I had a question about the grinder and they responded quickly too. It really is a joy buying specialty coffee beans and using this grinder every morning. The difference is obvious.
