As far as plastic cups go, it's fine. Now for the grand kids, it's really cool! Just watch how fast it changes colors when something cold (or hot) is added to the cup! And as you tip it to drink, it changes too! FAST! Kids find these fascinating! Adults? Well, it's a decent plastic cup.

My kids and I really enjoy this cup. So cool how it changes colors with hot or cold. I can check levels on how much they drink by just looking! The kids are drinking more to try and make the color change. Nice big cup too.
