This is an awesome product. It will keep fluids warm for up to 12 hours - and yes, I have drunk a coffee from it about 10 hours after I bought it... not hot, but definitely better than tepid. The shutting mechanism is wonderful - once shut, the cup can be chucked in a bag with no leakage... you've just got to be careful to make sure that the lid is properly screwed in. I tend to tip my cup upside down after filling it to make sure it really is in the treads. I love this, and have bought a couple more so that I'm never without one.

Great item, keeps my tea hot to the last drop! Love the internal thread to screw lid on, makes for an easier drinking experience compared to my old cheaper one!

These cups are just THE BEST! You can doze off a dozen times & have a slurp of hot tea each awakening - really does stay hot
