I was excited to find these big tumblers so I wouldn't have to refill my water several times a day. Such a disappointment! They do not hold ice all day and they sweat like crazy! If I lived closer to the sams club where I bought them, I would definitely return! I love the size and the handle, just wish they didn't sweat all over the place.

I love the size and durability of this 50oz tumbler. It keeps my ice water cold for a full 24hrs. I fill with ice over half full and fill to the brim with water and I have ice cold water all night and day. I do wish there were cute patterns or at least a purple one. For cold water longer, when not in use I do keep the tumbler in my freezer during the summer months without the lid on and then put cold inside when ready to use so I have very cold water when outside and I don't have to refill often with the size. I've had for 2 yrs now and it is still holding up like new

It works great as keeping liquids cold (don't know about hot) and fitting in a car drink holder. I have a couple of issues with the tumbler : 1. If you place it on a flat surface it easily tips over 2. The lid is not very durable - was removing the lid and it slipped out of my hand, it fell to the ground and broke into pieces.

I bought these cups after a coworker raved about hers. The ad claims to keep ice cold for 50 hours. I could not get mine to hold ice longer than a couple of hours. I find that my cup is rather on the heavy side as well. These are supposed to be just like the Stanley cups. Just cheaper. I think I will throw this one out and go back to my Yetti or Rtic. They hold ice and have the handle and are a tons lighter. Just not my cup of tea.

Just received this morning. Filled with ice and it's now 10pm & I still have plenty of ice. They are a bit heavy but no problem since there is a handle. Gonna get a lot of use with these! I am diabetic so I drink lots of fluid daily. With the size of these it means I don't have to refill as often.

These are very large and heavy. And 1 of my straws came damaged (crack/hole near the bottom).

I got, mostly, for my son to have cold water at work. He shared it works great

Great cup! Keeps beverages cold for an obscene amount of time! Great size!!!

Loved how much they would hold and the colors was amazing!

Keeps drinks cold for hours. It is large but fits nicely in my car cup holder.
