Title: Great if your drinking your coffee within an hour.
Review: After reading all the great reviews I bought this mug. I had previously bought 3 of the Thermos Nissan 16-Ounce Stainless-Steel Backpack Bottles. They worked great but I figured I try something new......I figured wrong. This mug loses its heat through the lid which you can feel is warm after you fill it. The cap is great because you can take sips with a push of a button but I like my coffee hot not just warm.
