Works As Advertised
 

I carried my travel-mug with my, rapidly cooling, 'sippin coffee' into an office appointment the other day.
My Physical Therapist exclaimed; "You have GOT to get one of these. It actually keeps my coffee hot for four hours!"

I did. It does.

I got mine in a two-pack from Costco but they are sold everywhere.

Cool, especially for cold beverages (I don't much care for hot beverages). Too bad my cars don't have cup holders...
