I seen these at the store and my 3yr old wanted them, so I purchased 2 of them seeing that they were 100%leak proof and they were on sale. I do like them but every single one of them leak. i have flipped the gasket over in the lid, still leak. I dont know maybe I got defective ones.

False advertising - I purchased these two cups for my toddler mainly because the box, and cups were labeled as “spill proof” which is a misleading claim and completely incorrect. By the time I got home and realized that whether I put juice or water the cups leaks. There is a gap between the straw opening and the actual straw size that is due to design rather than defect. Please! PLEASE do not purchase and waste your money there are a lot of products out there who actually serve the purpose. I also contracted the company to file a customer complaint and sent my receipt and everything after an extensive questionnaire they said they are sending replacement “lids” and only for one of the cups but I purchased 2 in the pack I purchased not to mention they WILL not send you the matching color. I wish I could have returned it to the manufacturer not the store, however they do not let you send it back to them. They claim bc you purchased it from Sam's. As a consumer it doesn't matter where you get it from, there is a design issue not a retailer issue.

Not leak proof. The top part of the straw detaches and can be easily removed by little one. Kind of a pain to clean. Pros: Keeps drinks cold and fits in car seat cup holders.

The cup is nice, but it is not 100% leakproof. Both cups have leaked several times when the cup has been knocked over. The handle is nice and we like the cup overall. It is light enough for my toddler to carry even when full.

[This review was collected as part of a promotion.] Unicorn toddler approved! Loving this cup so far. I like that it’s actually spill proof and the handle and straw makes my daughter drink it because it looks like “moms” cup. It’s heavy duty keeps drinks cold all day long and washes up great with no small areas that will collect mold. I really like these and will purchase for my son nexts.

So grandma got my baby a dinosaur water cup for Christmas, then it’s broken. Then it’s the end of the world 😅 since he only drinks his dinosaur water. So I searched all over internet and came across this set. They finally arrived yesterday, and my baby loves them. Funny thing he likes the construction one better than the dinosaur one😆 To my surprise, it’s much better made than most mugs or tumblers we own. The handle is connected to the ring around the body. The print on the bottle look pretty high quality, too. The straw feels nice, feels like silicone to me. And it can be hidden away. My boy really enjoys playing with it. Very happy for my purchase. Thank you.,

[This review was collected as part of a promotion.] This is a very cute tumbler design for my kids. It is leaking poof and features with retractable straw. It keeps my kids drinking cold all day and comfortable to carry around. It is easy to clean and light.

[This review was collected as part of a promotion.] These prints are so cute. Love the blue and pink combination. The straws are silicone and it keeps water and beverages cold for so long. Perfect for on the go. The material is great and sturdy. You can even put it in the cup holder for on the go. It also holds a lot of water for a toddler to go through half of their day! 14 oz is huge.

[This review was collected as part of a promotion.] These cups are very good. Colors are vibrant, and the designs are so cute, and they feel like 3D. The only thing is that it is not made to work with hot liquids. Other than that, great size, great quality, and presentation are pretty.

[This review was collected as part of a promotion.] These Ello cups are a number 1 favorite for me and my daughter. She loves the designs and colors. These are her top 2 to bring to school. They are also classroom safe as the do not spill or leak. I love them also for that reason. They are super easy to clean and put together. We also recently went on a camping trip and this cup kept her ice water cold the whole time. She dropped it multiple times and it is so durable you can't even tell. It also didn't open or spill. I am going to be getting these for the whole family. With the design options, ease of cleaning, durability, and its effectiveness, these cups are a win for everyone!
