rocky mountain tumbler is very nice. a little too big for my arthritic hands, but I like it anyway.
Doesn't keep my coffee as hot for as long as they say.
I am very disappointed that it doesn't keep my coffee as hot for as long as they say and I tried it once without putting hot water in first to pre heat the tumbler and then with doing a pre heat with hot water and 5 hours is all I got and about 4 hours into it, my coffee was already just about cold. I so hoped this was the miracle coffee mug because it costs a lot. Sorry I bought 2 of them.

Lid did not fit tightly, and if tilted the least bit, spilled easily .
