I have owned this coffee maker for approximately 6 years. It is used daily so it has had a LOT of use. The first few years that I owned it it worked just fine although the clock likes to reset itself sporadically. However, in the last year the coffee maker has been malfunctioning. The biggest thing is that it randomly leaks water all over the counter top. I have done everything I can to pinpoint why it's leaking but there seems to be no clog that I can find and no reason for the leaking. It routinely leaves grounds in the coffee and it also will only brew about 9 cups worth of coffee despite my filling it up to 12. I do enjoy the programmable feature, it is extremely nice to wake up to the smell of coffee but it doesn't do me much good when the coffee is undrinkable due to grounds or when I have to brew a new pot because half my water leaked out. I use a gold coffee filter if that makes a difference, I can't imagine why this would hurt the functionality of the coffee maker though as I have used them before in other coffee pots and they've always been problem free.
