[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!

I wanted to love these, but they arent suitable for younger kids. they also are not spill proof like they claim.

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.

Cute cup, drink stayed cold, but way too many pieces. Top Straw piece is easily pulled out by kids. They loved the designs but not well designed.

[This review was collected as part of a promotion.] Great quality tumblers. Durable, cute and the perfect size. I love the retractable straw design and how well they keep drinks cold. Easy to clean and very kid friendly

Most definitely not leakproof. Makes a mess of tipped over. Want a refund.

Horrible they spill and also very hard to clean make it great for mold

2 designs targeted towards little girls but only one for little boys? Not the best marketing decision. Perhaps a neutral 2 pack design and 1 for girls and 1 for boys would have been more wise.
