Not leak proof

Not leak-proof! I got it for my twin daughters because it claim it's leak proof. It's constantly leaking. I don’t have the package it came in that's why i don’t return it.

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.

Ok cup

Nice cups. I like that they hold a good amount of liquid, stay cold for a decent amount of time and that the straw goes all the way to the bottom of the cup. My kiddos love them. However, we have found that they do leak, quite a bit if left that way for any length of time. My daughter fell asleep in her carseat with her cup tipped and in the 20 minute drive home she was soaked from the waist down, her carseat was soaked and so was the seat if the truck. These cups will be used for outside and we will stick with our other leak proof straw cups for car rides and inside.

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.

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.

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!
