Keeps beverages warm, no spill
I wanted this item for three reasons:1) I spill coffee way too often on my desk2) My travel mugs don't keep my beverages warm for very long3) I wanted a mug with a metal interior, not plasticThe mug meets those three criteria.Additionally, the exterior metal stays cool to the touch - however the plastic top gets warm.I actually need to sometimes let my beverage cool before I put the top on, otherwise it's an hour before I can actually drink it.Very happy with this purchase.
