Query: Mr Coffee Grinder

This is the worst product I have ever used. In the description and on the box it states "it is great for coffee & spices", but the instructions state for best results "only grind coffee, do not grind nuts or SPICES"! It does not bring out the flavor of the coffee. I have read and re-read the instructions and do exactly what they tell you to do. I had a Cuisinart similar to: DBM-8 Supreme Grind Automatic Burr Mill. It was a VERY good product even those the reviews were not that good. I had it for almost 4 years and used it just about every day. Four years, everyday would be over 1400 grinds. I think it needed to be cleaned (never cleaned it) and started to have issues and then I think I broke it, unintentionally. Amazon is good with their policies and the products that they sell. I will be calling them to see if they can help me out with this piece of garbage.
