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.

These are really great cups!! First of all they are just super cute for kids. The colors are vibrant and the material is very durable. The lid has a little lock mechanism that will help with spills. I can see my grandkids using these for a long time and feel confident that these will hold up to the numerous drops, rolls and throws the boys will put them though. In addition, the Sonic design is their favorite!!

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.

The Hello Kitty water bottles set stands out with its vivid, eye-catching designs. Each bottle features bright, cheerful colors and adorable Hello Kitty graphics which I love as a collector. The high-quality, bottles ensures durability and resilience, making the bottles ideal for daily use. The vibrant colors are not only attractive but also resistant to fading, even with frequent washing. The sturdy construction means these bottles can withstand drops and rough handling. This set combines aesthetic appeal with practical durability, making it a stylish and reliable choice for Hello Kitty fans.

These water bottles are great! Fun designs that aren’t babyish but are still the character he wanted. And 20oz is a great amount of water for my 1st grader. The stainless steel keeps the water cold all day and there still ice in there. We love these, totally worth it!

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

Requested this item for my grandson going into his first year of full days at school. These were bigger than expected which is good. Love the locking lids to keep from spilling however wish they were spill proof with the lid open as well. Cute designs and love that they are sweat proof. Great quality and overall happy.

Disappointed in these. Water bottle functions fine and cleans up easily. But the print is terrible quality. We have only hand washed these and the print started chipping off after only a few weeks. This is my son's school bottle, so it does go in his backpack. But expected better. The silicone bottom also comes off super easily. Already lost one of them.

The paint eventually starts to wear off, but long before any of the pieces need to be replaced. The spout and seal are difficult to remove for cleaning. The silicone (?) ring on the bottom, presumably meant to make setting the bottle down less noisy, falls off and gets lost. They do leak if not kept upright or the seals not seated properly. Otherwise, very good, long lasting water bottles that keep cool, however I will be reluctant to buy similar zak bottles again due to the paint looking just awful after long term use. The cups are going strong but look so trashy. Also, the paint does not appear to be covered by the warranty.

Great Quality and Durable water bottles from Zak. The straw less, snap open spout is easy for my kids to use and drink from. The bottles are sturdy, the right height, and don't tip over easily. I would definitely purchase for all my kids.
