Color Changing Cups, 5 Pack 24oz Plastic Tumblers, Reusable Iced Coffee & Smoothie Cups with Lids and Straws for Parties and Travel

Very nice cups. I have not tried hot liquids in it so I have no idea if it changes colors or holds up. For cold liquids it is the perfect size. The lid stays on and no issues with it popping off any of them when carrying. Very pleased with these

Absolutely love them! Love the color change, tight fit oof the lid.

You need to allow it a few seconds to have the color change take place! It works with COLD liquids, not hot! It's perfect, this is my favorite one!Note: lids and straws are not thermal and do not match perfectly. You can buy color changing straws from other suppliers yet they are not extremely sturdy and may yield different colors.

The colors of these cups are very pretty. I don’t mind that the pieces don’t all “match” because it looks good mixed up. The cups do change color with cold liquid in them. My only issue is the lids do not stay on. They don’t lock in. This is a good cup for the beach so sand doesn’t get in drink though. I still like them a lot. Lightweight and easily portable.

Good quality for the price and works as expected. I was worried the lids wouldn't fit properly or would leak but none of those issues have come up. I would like to see them in a different color set but that is just me. They also don't insulate much and can be hot to hold but these are not for that purpose. The size is good for drinking a cup of coffee in the morning without having to refill it. I would buy this again if I had to.

Cup quality is good for the price. Lids fit well. Color change is either too subtle or goes the wrong direction (cold beverage cup but changes with hot liquids.) If you need decent cheap cups these are fine. If you want color changing cups look elsewhere

Great cups. Someone shoved the lids inside the glasses so half the lids were too bent to use. Otherwise , fantastic.

Absolutely love everything about these cups! They are strong and not flimsy, which is great. The size is perfect and it doesn't leak. My daughter loves the color Changing features. It works great for cold drinks.
