Super cute

[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.

You NEED this!

[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!

Cute

[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 !

These are such cute cups.

[This review was collected as part of a promotion.] These are such cute cups, my daughter and I both love the designs! They are really easy for her to use - I love that the straw can be covered for germs. The straw itself is flexible and comfortable to use. It's leak-proof and dishwasher safe which are both great things. They also fit in the car cupholders!

I really like this product

[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

Best cups we have tried!

[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!

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.

Fun and efficient!

[This review was collected as part of a promotion.] I received this product free from influenster in exchange for my honest review. These ello cups are cute, sturdy, and prevent leaks. Turning the dial on top of the lid pulls the straw into the cup and seals it to avoid leaked when turned or dropped. The cup itself is not overly heavy and perfect for kids on the go!

Amazing cup

[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.

LEAKS EVERYWHERE

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.
