Great lil cup, perfect size for my cup of coffee, morning, noon, and night (decaf at night) probably won't keep hot all day but I can't keep a cup of coffee that long anyway lol. Had to order my wife one after she seen mine, and she has a bigger thermal cup that will keep it hot all day but it's really too big (not for our Keurig) just too big in general. Thanks Keurig love my coffee and my cup .
