Title: tight and pretty hot.
Review: Hmmm... wrong title? Anyway, I used to nuke my coffee near to boiling in my old thermos sippy cup so it would be warm 20 minutes later when I sipped it on the train. With the Contigo I actually wait a bit before I pour the coffee in so it won't burn my lips when it comes out. I drop this mug in my backback, sideways or upside-down does not matter: no leaking. Need some wrist strength to twist the top on tight. Good product. Buying it in red helps keep the coffee extra hot; I presume buy blue for mai-tais.Not as heat-retaining as some dedicated thermoses but that is partly a function of volume vs. area of container wall.
Is this product review negative?
