My wife likes this machine (our fifth or sixth Bunn in 20 years of marraige) more than I do because I often leave the coffee 'til it has cooled too much.
Positive Product Points
Thermal carafe (see negative, too).
Negative Product Points
Coffee cools surprisingly fast after brewing.
I've found that who manufactured my paper filter affects overflow when I make ten cups. (When fewer cups are brewed, the thermal carafe doesn't keep it hot as long but, of course, fewer cups usually are consumed sooner). The handful of free Bunn white filters that came with the machine did not overflow. The store-brand unbleached filters I used to buy sometimes did, but not always. Until I complained, many of the store-brand filters had semicirclar bites taken out of them because, it was explained to me, the dies that stamped them "missed." I would return the 5-to-30 per cent of those filters that were defective; the store would give me a whole new box -- an abuse of their policies calculated to prompt them to minimize or correct the problem which, for a while, they did. Now, I use Melita's white or unbleached (preferred) 8-to-12-cup filters and have not experienced overflow. As for the phrase "not experienced:" it doesn't mean I never, never see small grounds in the bottom of the basket when I dump it; but by some mechanism, no grounds of any size get into the coffee I pour.
Finding it took some searching among all the cheaper offerings in Target's housewares asile, but otherwise my experience was unremarkable.
