I received this coffee grinder as a wedding present a few years ago. The grinder sat in storage for ~18 months while we were moving and setting up in a new home. Two months ago I unpacked the brand new unit and started grinding coffee beans. After using the grinder 4 times, it started to smell like burning and after the 5th use the unit started smoking. I call Cuisinart with my compliant, but since I had the unit for 18 months and never used it, it has passed its 18-month warranty. Don't buy this coffee grinder unless you wanting your coffee beans to be re-roasted while grinding.
