I like these a lot. I only use them in the house & they keep iced drinks cold for 36 hours plus.

Absolutely love! Keeps ice all day.

The cups are beautiful and keep your drink cold, however, they do not keep ice frozen.

I a good 4O oz cup that keeps water cold for 12 hours.

Love these mugs. They keep drinks ice cold for hours.

I love them. Keep drinks cold or hot

Great product, just wish the lid was tighter

Great cup to keep your beverages hot or cold

Love the size of them, the handle the bright colors

Love this tumbler! Fits in my car cup holder, keeps drinks cold and is fabulously large!
