Title: Best coffee mug, ever
Review: I have tried many different types of coffee thermoses/mugs, this one is easily the best I have ever owned. It is completely sealed at all times except when you hold the button in to sip your coffee, so it is both leak proof and highly efficient at keeping your coffee hot (it keeps my coffee hot much longer than any other mug I have tried). I have one of these at my office and two at home (because I really like my coffee hot). I've never written a product review on amazon before, but this product is so good I felt compelled to write something.
Is this product review negative?
