I would give zero stars if I could. These cups are horrible. They literally POUR out water if they're dropped, thrown, etc from around the base of the straw as well as the straw itself. They're only leak proof when the straw is put away with the sliding mechanism. I don't know who in the world designed these cups but they should go back to the drawing board.

[This review was collected as part of a promotion.] If there was an option for 20 stars I would rate this product 20 stars! This is the best! I would highly recommend! My toddler and I both love. Cute and doesn't spill at all- also dishwasher safe which is always a plus in my book!

[This review was collected as part of a promotion.] I wish i had gotten the other designs. But these are great for kids. Once you twist the lock they are spill proof . The straw is bendy so it dont hurt my kids. And the water stays cold for a while !

[This review was collected as part of a promotion.] These are absolutely adorable. My daughter loves them so much. It is the perfect size for a kid her age. She sees me with my water bottle and she just wants to copy me and these are absolutely perfect. It gets her to drink water and she gets to act like mommy with her cup! The designs on the cups are so cute! Very good quality.

[This review was collected as part of a promotion.] I received the Ello Oasis cups free in return for my honest review. These are absolutely adorable. The colors are vibrant and the design is perfect for any girl. They are light weight and the perfect size for kids (or adults) hands. The lid has a retractable straw that rises and lowers. The straw has a seal on it so when not in use they won't spill if tipped over. They kept the drink cold for a long time as well. They are easy to wash and dry. My daughter absolutely loved these. Highly recommend.

[This review was collected as part of a promotion.] Wow this is super adorable! Love the stainless steel and retractable straw. Great for on the go. No leaks as well! It is a little difficult to clean under the lid due to the lid retraction mechanism but overall solid product. Might be a little heavy for a kid though.

Junk. Be careful abou new products at These big stores. Cute design on the outside but it is only an expensive cup. it doesn't keep anything cold for more than afew hours. The straw concept is cumbersome and if you don't want to use it, There is no other top? Waste of money.

[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.

[This review was collected as part of a promotion.] I really like this product. The design is beautiful, and the raised 3D illustrations are sharps and very cute that kids love them. The leak-proof design is very smart, from the lid to the straw. The cup is not too heavy. Overal, this product feels hight quality. Worth the money and I will continue to support this brand

[This review was collected as part of a promotion.] These cups from Ello Oasis are super cute. They were easy to use. I love that there was ZERO leakage! Being able to carry this in my purse and not having a to worry about it spilling all over everything. They're super easy to clean. I love that I received two so that it's easier for morning and lunch because we all know cups and toddlers tend to get left in different places lol.
