Review (5/5): Miracle Mug!! Keeps ice for hours!!
Wow! My family used these to a recent trip to Mexico and I am shocked at how cold they kept my drinks in 90 degree heat. Even after two hours, my drink still had retained most of its ice even when I had the mug sitting in the sand, in direct sunlight next to my beach chair. Amazing!!! I 100% recommend this mug if you like your drinks to stay ice cold. One morning, even after sitting all night, when I went to clean out the mug it still had all the ice cubes in it!! It's like a miracle mug.
