[This review was collected as part of a promotion.] this pack of two Ello stainless steel bottles (12oz) for my daughter is amazing !! I’m thoroughly impressed. The insulation is excellent—it keeps her water cold for hours, even during outdoor activities or in her schoolbag all day. At 12oz, the size is perfect for a child: not too heavy, easy to carry, and fits well in cup holders and backpack side pockets. The bottles are extremely portable, making them ideal for school, outings, or travel without adding bulk or weight. The leak-proof design truly lives up to the promise. I’ve tested them upside down in bags, and not a single drop leaked. That’s a major relief for school and travel. Cleaning is easy too—thanks to the wide mouth, I can reach inside with a bottle brush or just pop it in the top rack of the dishwasher. The durability is outstanding. They’ve already survived a

[This review was collected as part of a promotion.] I feel like this could get 5 stars just for the design. The character designs are adorable and my kids screamed from excitement when they got this. It keeps their beverages cool for hours and I love that you can lock the lid to keep from spills.

[This review was collected as part of a promotion.] I like these as they are small and portable. They are leak proof. Cleaning is very hard as there is a deign flaw of having pull the straw. It’s durable and well insulated. Just don’t like the hard plastic horns. They can hurt if they press on something.

[This review was collected as part of a promotion.] Our son loves these new cups. The lock feature is great for preventing spills. The straw inside is flat, with silicone feel, and my sons loves that. The other cup he had contained a harder straw, but this bendable one allows for more flexibility. It keeps his chocolate milk very cold, which he loves. It also allows for a nice serving size. It has a small handle on the back, which is great for him to carry around. These were a hit!
