Query: Travel Mug Great!

I have my own travel mug by Nissan that I bought YEARS ago and it still keeps my coffee hot. I just purchased this one for my husband (after a few years of buying cheap ones that just didn't cut it.) It definitely keeps his coffee HOT and it's easier to clean than my old one. The key is the interior of the cup. Definitely worth the $25.
