It keeps all of my cold things cold and my hot things hot for a very very long time. Not only is it attractive, it's easy to clean. And I do not have to worry about accidentally knocking it over and spilling stuff everywhere! Mahalo nui loa!

Stylish, my favorite color, nice a big for a long morning commute, and fits in the cup holder. What more could I ask for?
Answer: only that it is filled with Kauai coffee ; )

The design of the mugs is very nice and cheerful. Size is perfect and I use it mainly for water / iced drinks which it is most suited for.

I poured the last of my cold soda into the and took it with me in the car to run some errands. After getting back home keeping groceries and finishing my chores. I needed a cold refreshing drink. I remembered that I poured the last of my soda into into my mug. I went back out to my car to retrieve my cold soda in the mug. After 3-1/2 hours I was expecting to pour out the warm soda, but to my surprise. My soda was still cold. It sure was nice to have a cold drink since I didn't have any cold soda left at home.
