“I absolutely LOVE my healthy human cruiser tumbler. I use it nearly every day for iced lattes/iced coffee/smoothies, etc. It is incredible in its ability to keep my beverages cold. I haven't yet tried it with hot drinks yet, but I'm sure its fantastic in that department as well. Just the other day I had made an iced latte at 7:30AM, and when I finally got home at the end of the day at 6:00PM my cup still had solid intact ice cubes in it. Highly recommend this product. It's also incredibly easy to clean!”
