THERMOS Stainless King Vacuum-Insulated Travel Tumbler, 16 Ounce, Matte Steel

Great insulation! Use it every day to keep iced water cold and ice cubes survive throughout the day. I have used it overnight and ice cubes have not melted the following morning. It also keeps my tea and coffee warm. After 2 years of using this travel mug, I have to say that it keeps liquids colder for a longer time than it keeps them hot.

I have purchased this brand of mug for years. Keeps my coffee warm for hours. You can drop it with the lid closed and it won't spill a drop. Everyone needs this mug if you travel.

I’ve had one like this for years and love it for how well it works. Easy to hold, doesn’t leak when closed, even when dropped or tipped over. Hot beverages stay hot for hours. I take it with me golfing in all weather.

Great cup. Coffee stays nice and hot for several hours.I don't use it for cold drinks, but I'm sure it works just as well. Sits in your hand comfortably. Nice weight. Fits perfectly in car cup holder since it has no handle.

I thought that this was the perfect coffee mug. It keeps coffee hot for hours, the lid is secure and the mug fits easily in the cup holder. But while most travel mugs have open and closed positions, this one rotates to open, closed, open closed, open, closed, etc. in both directions. Because of this feature, the user has to look at the lid while driving to determine if the “open” or the “close” position is showing. The writing is small and difficult to see and this leads to distracted driving. Combine this with stop and go, rush hour traffic and it spells trouble. Nice mug, otherwise.

Best coffee cup I've ever owned if you knock it over you don't lose a drop keeps coffee hot for about 8 hours

Love this mug. It keeps liquids cold and is leak proof. Everything I need.

It preserves hot coffee temperature for many hours. Nice tight seal. No dripping, leaking, or burning mouth like some other bands. Easy to clean. Easily fits car cup holder.
