We've had this coffee maker for a couple of months now and we're giving up on it. From the lack of water filter, to the poorly thought-out two-piece top, it has design issues.What finally did it in is it started overflowing. We had not had this issue for the first ... well, up until last week. After a thorough cleaning, it still overflows. We used all the tricks people have listed here, but it overflows both inside in the filter and in the funnel to the coffee pot itself.So it's done. Hoping to move on to something well designed and actually works.
