Thought I would post this here because so many coffee and tea drinkers make their coffee or tea at home and take to work, or want to keep it hot for a variety of reasons. I have previously had the Contigo mug that QVC and other places sell, that is supposed to be so fabulous. If it keeps my coffee warm enough to drink for 2.5 hours I'm lucky.
I got tired of this, so started googling for "best" at keeping drinks hot. I came up with the Zojirushi SM-KHE series on Amazon. They come in different sizes and colors. I bought the 16 oz size. Not cheap, but I took a chance. It works! I put hot coffee out of a Keurig (home or office) into this thing and it is still actually drinkably hot/warm 5 hours later and would be at 6 hrs too. So impressed. I am flu-ish and took chai K-cups to work today. Made them at 8:30 and it was still almost hot at 3 p.m. Wow.
