This tumbler is amazing. I keep ice water in mine. It will hold ice for about 36 hours. My drink is always super cold. It fits in my cup holder of my car and thats plus.

I was so excited when I saw these tumblrs in store. Only one of the tumblrs kept ice overnight and the other one melted. The cups are nice but still So disappointed.

Huge tumbler that holds plenty of water, but not too big or bulky! Love the lid. Keeps water cool. Favorite tumbler that I’ve bought yet and will buy again. And the price is such a deal!!!!

Does not keep drinks cold for very long. They look great. I wanted to love these so much because of the handle and the size. They say they keep drinks cold for 50+ hours, more like 5+ hours. They don't even keep drinks cold for overnight. If you like watered down drinks because you have keep adding ice then you would like this travel mug.

I purchased this cup because it claims to keep drinks cold up to 50 hours. This is not true with the 2 cups that I purchased, it didn’t even keep my ice for 24 hours. I thought maybe if i removed the straw so air wouldn’t get in it would work. But that did not work either. The only reason i would give one star is because it fits in my cup holder in my car. Other than that i would not recommend any to purchase this product. I should have read all the reviews before i purchased it.

I bought a set last week & I'm not impressed. They don't even hold ice overnight, in my house. Yesterday in my car, the I've melted in less than 2 hours. I will be returning this tumblers. I have a cheap off brand from TJMaxx that works much better than these.

I love these cups I filled my cup up with ice and water at 2 pm went and swam outside in 90° heat for hours still had ice sat it on the counter next day same time went to fill it up for my swim it still had ice and very cold water. I have even took it shopping with me and it staying cold in the hot car throughout the day. It also fits in the cup holder.....a plus. But also has a rubber like bottom. Will purchase more!!

These a perfect! Perfect size, perfect modern design, perfect price and they fit in the cup holders in my GMC. Love!

Love the size and that they fit in cup holders. However, they do not keep my drink cold as long as other tumblers I have. Bummer

We love them so much that I bought a second set. I will most likely buy for others in the near future. They have held up nicely for a year.
