Input:
This is by far the best travel mug I've ever owned.. It keeps beverages hot for hours, and cold for even more hours..  The design for the lid is awesome.  Just like drinking from a mug with no lid... Plus if screwed all the way in you can throw it in a bag or on the truck seat because it will not leak..  I'm thinking of ordering a 2nd one as a spare in case something happens to this one!!
