If you're a "java junkie" like me, this product is just what you need! The carafe keeps my coffee HOT for approx. 4-5 hrs. (I say "approximately" because I consume SO much that I make a fresh pot every three to four hrs.) I just ordered a replacement as my original thermal carafe (also from Gevalia) finally gave up its ghost last night when I was cleaning it (thermal liner broke). After 20 yrs of continual daily service, I can't complain!
