[This review was collected as part of a promotion.] My boys love these!! 4yo and 2. 5yo. The color changing is a fun bonus. The lids are a small twist on, which confused both my husband and I at first but I prefer that instead of pop on/off! We will definitely be migrating most cups to these when they are eating meals!

LEDs don't stay on cups there leak

The lids are difficult to screw on. My kids aren’t able to get the lid off or on themselves. The boys love the color changing.

We have used these for years for all of my kids. I am so stoked to see these are still available through Sam’s!

My kids love the color changing!! I really like that it’s a twist top, so my littles can’t just peel up the lid!

My 4 year old grandson loves these cups!! He gets so excited when he fills them up with ice and water or juice, and they change colors!!

Good cups, nice colors, sturdy, and great grab bag gifts for parties. Only thing is most people don't know they are twist top and try to pop them open which obviously doesn't work.

Excellent product and value. I love how sturdy they are and the size is perfect. My granddaughter loves that they change colors when cold drinks are in them. She feels like a big girl with the straw. And they wash up great in the dishwasher.

We love these. I bought them with our three year old granddaughter in mind but everyone uses them. We've washed them in the dishwasher and they came out fine. I'd buy them again!

These are cute and kids like the colors but use is an issue. Too change the color you need cold beverages including ice cubes. The tops leak and fall off with toddlers and make a mess. Screw on tops wouid be more practical.
