Review on Keurig Contigo Autoseal Coffee Travel Mug, West Loop - Vacuum Insulated with Easy-Clean Lid - 14 Oz Capacity - Silver by Lance Gunn

Almost everything in this mug is very durable. It has a pleasant shape, the lid is comfortable, does not leak. Unfortunately, this mug has a fatal flaw. The coffee doesn't stay hot for long. It says it's vacuum insulated, but I just can't see it. When I filled it with hot coffee, the mug quickly warmed up on the outside, suggesting there was little to no insulation. I'm sending it back and looking for another mug. I want one that fits under the Keurig Supreme Plus. If the height of the mug is not an issue, a thermos is an excellent thermos that will keep the heat for a very long time. This is the one that has a little button on the top of the lid that opens and closes the seal. I would not recommend this mug to anyone planning to use it as a travel mug to keep their coffee hot for longer than 30 minutes to an hour.
