Better no spill cups for kids than any of the other brands including yeti. Much easier to clean. No spills. Nothing to brake. I won’t have to replace them till they wear out. Great product finally at a much better price than Stanley or yeti, twice as good.

My daughter is crazy about Lilo and stitch and loved these water bottles. They are really durable, and they don't leak. She carries them around with her everywhere, and I have had any issues with spilling. The design is super cute and really high quality product

The grandchildren love them because they have Spiderman or Disney Princesses on them. Grandma loves them because they are practically spill proof. It's a win-win for us!

I bought the Hello Kitty set for my daughter & she just loved them. The tumblers were not to big nor too small they were just right. Not only are they durable they keep your drink nice & cool for hours.

This tumblers are so adorable. The color, size and the size of the handle are perfect for small hands. The design are so cute , all the Princesses . Love the color too , peach and purple. But most of all it’s leak proof. So you don’t need to worry in the car seats or strollers .

I absolutely love these cups! ZAK is a great brand of cups and I really love how they keep things cold for a long time ! My girls use them at daycare and school and they keep their ice all day long. The Stitch print was an extra bonus for them! Very cute !

How cute are these insulated cups! I bought these to give to my students as a reward for good behavior. I decided to wash them and put ice in them to see how long the ice would stay solid and I was pleased to find out there was ice for many hours! Well made and super cute design! I’d certainly buy them again!

My daughter really likes these cups and so do I. It holds a good amount of water and keeps the water cool. The inside straw is detachable so it can be washed properly. It does require a decent amount of force to suck the water out due to it being a spill proof straw. I have noticed if there is ice water in the cups and they are left on their side they do leak out of the straw a little bit.

These tumblers feel like a good quality product and they look great as well. They do keep drinks cold for a long time (see photo of ice water after 14 hours as a test - there was still plenty of solid ice left!). The straw assembly pops out easily for cleaning and they are top rack dishwasher safe which is a bonus. These also don't spill if turned over due to the vacuum sealed lid/straw design so very kid friendly.

These were very cute for my 10 year old nephew who loves Minecraft. I liked the 16oz size and it does insulate cold very well. The spill proof straw is a great idea and the top twists to close which is nice. The downfall is the straw. It’s a rubbery material and my nephew chewed on it. It’s also hard to clean. Overall a good product, but I will need to get a different straw.
