I use this triple-insulated stainless steel thermal bottle all the time. Since it's summer, I've been using it for cold drinks. The drinks stay cold and what's really great, is that even when I put ice cubes in the thermos, my drink gets super cold but doesn't get diluted and tastes like I just fixed it. I'm sure it will work as well for hot drinks.
