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 claim “spill free” IT DOES Spill

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.

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.

Not leak proof

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.

my two year old loves it so much

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.,

Loving this cup!

[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.

Leak proof in style!

[This review was collected as part of a promotion.] Perfect size and weight for the little ones. My almost 3 year old and 6.5 year old were big fans! Great quality and design. Love how the straw hides away! So far no leaks! The lid and straw are easy to put together. Love the designs as well.

Must have for toddler and kiddo

[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.

Great cups

[This review was collected as part of a promotion.] These are great 14 ounce cups. This cup survived Its day of first grade with no leaking. Pay attention to the “fill line”. You don't want to over fill this cup. The handle is great for transporting. It's easy to open if she needs to refill during the school day. The best part is that this cup fits in the cup holder of their car seat. I won't have to pass water bottles back and forth in the car. The quality really seems like it's there with these two cups and they are easy to clean. The color and appearance is really great for both my son and daughter. If you're in the market for new cups this is definitely a great option.
