I bought this travel mug on a whim about a month ago after my husband lost his go-to mug. Seriously, I'm so glad he misplaced it. These travel mugs are incredible. They keep beverages hot for up to to ten hours and are leakproof. You can turn it upside down and it won't leak a drop.
I've never owned a mug that even comes close to this. In fact, I went back and bought us three more. Perfection!
