Query: Overflows easily, pieces broke

I was very excited about this product - saving on electricity was a biggie for me. The quality of the coffee was good, but as noted by another reviewer, the machine is finicky. It overflowed a number of times, I'm not sure why. I changed to a paper filter, instead of the gold plate permanent one, and that helped some, although didn't completely eliminate the overflow problem. The piece that is at the bottom of the filter holder broke within four months. It was not fixable at home. Without it the water flowed too fast through the coffee and into the carafe and it was very weak. I give the carafe four stars! Very good, holds the heat well. I've thrown away the brewer and now pour the coffee brewed from another cheapo coffee maker into the carafe and it stays hot, tasting good for a couple of hours.
