Query: Cuisinart - tough to clean

While the combined grinding and making of the coffee in one unit is a great idea, the mess that it created was a pain to clean up each day. The grounds would get caked in on all three removal parts and each part needed to be cleaned before using again. I had the product three months and it quit working. The good thing is that when we call Cuisinart's 800 number, they told us to just return the item to the store that we purchased it at and we got our money back.
