It kept my warm water warm even though it had been put in the fridge. I left a cold drink on the counter it stayed cold.

This tumbler is top quality and wow it keeps my ice frozen for several hours it's amazing! The graphics are sick I've purchased many of these tumblers to use in a giveaway for a group I sponsor. They go crazy over these!

I'm Soo Loving this Medusa 24oz Tumblr it's my Favorite, and I just love The Detail on the it.. I Love How It really Keeps my Drinks Cold in it for a good while and Im sure it does the same for Hot drinks too, Best Product I bought So Far from VF

Amazing! Took it to work and got compliments. I even keep it next to my bed for those middle of the night water cravings.

Great quality! The water bottles keep ice all day and the shirts are fantastic

love this tumbler

Usually these kind of cups are just cute, this one actually works! My ice stays frozen for at least a day or two.

This tumbler is awesome!! Just like pic! Keeps drinks ice cold for HOURS!!!!! Love it!!!!

I literally put ice in this baby like 8 am and I promise you the very next morning still had ice in it from the previous morning I work in the heat so I am loving this!!!!

I've never had a better tumbler/thermos in my life. Kept my water ice cold (with my ice still there) for over 6 hours at work. I was even more impressed that it managed to keep soup pretty hot for the same amount of time.
And on top if it all (along with the amazing design), no spills or leaks!
