Does what it is supposed to do.  Only quirk is that once the keep hot time expires, you cannot turn the maker on again to keep it hot past that time.  In order to overcome this "safety" feature you must add a bit of water to the reservoir.  This would not be a big thing except you cannot add the water after you have made the coffee and the time has expired until you remove the coffee ground container and the container that holds the liquid coffee.  There is no way to add the water without doing so from the outside.  A minor problem if you do not want your coffee kept hot longer than 4 hours.  In spite of that one quirck, I would buy this product again and recommend others buy it too!
