[This review was collected as part of a promotion.] These cups are insanely adorable and the size is perfect for my three year old. The silicone straw part however is not made to fit tightly into the lid though so these leak a lot. I bought two cups and they are both this way so it’s a design flaw. I compared the new straw lids to mine that’s very old at this point and the part is just not made the same, much more flimsy and not fitted. It seems like they got a new manufacturer and either missed the fact that these don’t fit well or just ignored it. It’s annoying though as I only really like Hydroflask compared to the many insulated bottle brands but if they continue to cheap out I may have to move on.
