This is my third Cuisinart Coffee maker.  I really like them.  I have had a strange issue with this one. It has overflowed several times.  The first couple of times were my issue, didn't press the filter holder down securely enough the last one can't really figure out what happened, the top was sealed well, but still had a major grounds issue into the pot.  But we are moving on. I know takes a while to get used to how things work.
