Super cute! Great for kids to to take to school. The flip top keeps it hygenic and spill proff while being easy to wash. It worked awesome at keeping drinks cool. I put cold water with a little ice to see how it would keep. I left it in our vehicle in temptures that felt over 110 degrees for over 8 hours. There was no ice left but the the drink was still very cold.

My 15 year old daughter loves Hello Kitty so when I saw these Zak 20oz stainless steel straw bottles I knew I had to get them for her! She was extremely pleased. She loves how there’s a push button lid that locks and it covers the spout to keep it clean. The Hello Kitty design on these is fabulous!! The handle makes it easy to carry around. They are very well made and she plans on using them for school this year.

If you are looking for a leak-proof water bottle that prevent bacterial growth on the drinking surface, look no further. This water bottle is easy to clean, has a push button to open and comes with a handle for easy carrying. Plus it comes in a set of two 20oz bottles.I love the Sonic the Hedgehog design.

My daughters got the hello kitty design of these water bottles and I don’t think I’ve ever seen kids so excited about water bottles. They’re large enough and perfect size for a child (mine are 4 and 6). They’re super cute in design and quality wise they’re great. The spill proof design is also great for us parents. I love these

These Zak cups are SO cute and sturdy. They’re going to be great for my daughter for school and traveling. The lid is great, it can be easily locked and unlocked so that there’s no spills at all. It definitely keeps drinks cold for a while! The fact that it’s a straw system too is something my daughter loves. I would definitely recommend these. We got the Hello Kitty designs and they’re adorable!

Wow, wow, wow! These stainless steel water bottle set is the real deal. My son is in love with the Spider-Man one. Super easy to clean up and it even has a carry handle on it making easy for my son to grab. Love that it has a lock feature to prevent it from opening accidentally and spilling water everywhere. Definitely recommend.

My son loves these water bottles. He is a big fan of sonic so we ordered him sonic bottles. They are so well made and easy to carry around. They have kept the water cold for a while even in this hot summer heat. The lock on the top really help keeping his backpack dry so it does not accidentally open in his bag.

This water bottle is sturdy and well made! It is easy for a child to hold and close when not drinking water. The lock for the cap is a good feature to avoid accidentally opening just in case your child carries their bottle in their back pack. Cold water will stay cold but not as long as I'd like. One other con would be the rubber drinking spout which can be slightly harder to clean. Overall, the quality is great and will last a minimum of the school year.

The design of the cup is good and the graphics are really nice and colorful. There is not any grip material on it that would have been a nice addition, to prevent from dropping it easily. Nothing special or different about it than any other cup but it is an awesome cup for the little ones that love Bluey.

These bottles seem pretty solid and time will tell after being used for about a month with my 7 and 8 year olds. They've dropped them many times and a few scuffs only. Zak is a known brand for reason. These vottles are perfect size for the age and plenty of room to keep them hydrated while at school. It says 3+ but they seem a bit big for a 3 y/o in my opinion. These are meant for cold liquids only. They keep drinks cold for half day at room temp in my application. Perfect for back to school.
