This is the first time I've left a negative review for any product, but I'm so frustrated with this coffee maker, I felt I needed to warn people to stay away. There is a spring valve at the bottom of the filter that is supposed to open and close depending on whether or not the carafe is underneath. In ours, this will jam and water will overflow over the top of the filter and all over the counter. Other times, it will remain open when you pull the carafe out to pour before its done brewing and coffee drips all over the machine. Contrary to some of the positive reviews telling you to ignore bad reviews, this has nothing to do overfilling, just a poorly designed mechanism. Apparently some people get lucky and get a good version, but we weren't lucky. Ours is crap and its time for us to replace this expensive and frustrating coffee maker.
