Great design and function!

I love that these cups fit in a cupholder. The handle makes it easy to carry. Beverages are kept cold overnight. These are spill proof when the lever is maneuvered to lower the straw. However, if it gets tipped with the straw in an up position, the liquid does leak. Overall, I have really enjoyed these tumblers. The price point makes them even more likeable!

Not for hot or carbonated beverages

Love the design, however the store description doesn't align with the packaging. Store description says this cup is for hot and cold beverages and the packaging says “Not for use with hot or carbonated beverages.” I give it 2 stars since I purchased it with my morning coffee in mind and am disappointed.

Fine

The straw will not go down if you have ice in your cup
