Customer Reviews

Kept My Ice Water Cold All Day

"I got the tumbler in Neon Blue. I like the bright blue color with the matte finish. I’m actually surprised that the ice stays all day. I took it into a day long business meeting and it kept my ice water cold all day. Of course I did have a couple refills but it never went warm on me."

Attractive and Reliable!

"Great-looking, highly-functional tumbler. I get a lot of complements on it!"

Tightly Seals and Attractive

"One thing I’ve been struggling with having a tumbler is that the lid might not stay close as tightly as a water bottle. The lid of this tumbler doesn't have such issue. Although the water may still spill from the small hole in the lid, I don’t really have to worry about the spill/burn situation as long as I don’t fill the tumbler too full."

Great Insolation and Easy Cleaning

"This is my new favorite cup! I fill it up every morning with my own smoothie that I whip up at home and it’s able to say cold throughout the day. When I finish my smoothie, I just give it a quick wash and refill it with any beverage I want (usually coffee). It’s great that it’s able to stay warm or cold for as long as I need."

Love the Silicone Straw!

"Perfect size. Love the marble print. I have sensitive teeth to cold water. My other tumbler also has a stainless straw and it catches up with the temperature of the beverage so easily that my teeth hurt everytime I drink cold water from that tumbler. This tumbler has a silicone straw tip on the straw and it is really helpful to prevent the straw from getting hot or cold. Plus I can chew the straw and it’s still in good shape."

Easy to Carry. 12 hours of Insolation

"This is the best tumbler I have ever owned. Keeps ice and drinks cold for well over 12 hours!!!!! And it doesn't sweat at all. Great for travelling. Super easy to carry in my bag and also fits well in my car’s cup holder. I have come back to order another."
