Does not keep cold as long at it says. I bought these cause I kept leaving my other brand tumbler at work. They do not hold cold at all. Filled with ice and water at 7:30 am and at 12:30 pm most of the ice is melted. My old tumblers held ice over 24 hours. I do enjoy the bigger capacity and wider straw, but not worth to buy again.

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.

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.

Great cups that stays cold for 50 hours. Kroger has the purple reduce cups.

very large tumbler

Good size. Fits car cup holder. Drinks do not stay cold for over 3 hours.

I love Reduce! Why I own 9 of them!!! I can tell you they are worth it! They do keep drinks cold! I do smoothies and it keeps them cold all day.

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.

I have 5 of these in different colors and would buy more! Keeps drinking ice cold for more than 24 hours. They are also comfortable to hold. And the price... perfect.
