My previous coffee grinder was the exact same Cuisinart grinder that had been past down to me from my parents. It took thirty-eight years for that same model to start to wear out. This new grinder of the exact same model works top notch just as the first one did for the thirty eight years. Wonderful grinder at a great price. When this one starts to wear out after about fourty years I'll buy another. Thanks to Cuisinart for top quality products!
