These are very nice! They keep drinks cold for well over 12 hours and there is no condensation. They do not leak at all, even when shaken. The pop open covers are lockable as well. The decorations on them are very cute and suitable for both boys and girls.

This two pack of travel cups was just what we needed. My youngest two daughters had just broken and lost their travel water bottles when we found these. I love the locking option and no spill top. Having the straw makes it easy for them to sip and play all at the same time. They adored the very cute designs too!

These are really well-made bottles, and they don't leak! The flask is well-insulated and doesn't get any condensation even when there is ice water inside. The lid snaps shut and has a lock switch to keep it from coming open. Even when it is open, you have to almost bite to get your drink to flow. With the snap lid open, this bottle still didn't leak when it was tipped on its side. It's hard to imagine a better bottle for little kids. The flask is made of metal, and the lid is some sort of plastic/rubber that is soft but not slippery.

I recently got the Zak 2-pack tumbler set featuring adorable dinosaur and forest prints, and I couldn't be happier! The size is perfect for little hands, making it easy for my toddler to hold and drink without fuss. The vibrant designs are a big hit—my child loves showing off the cute prints! The handle is super practical, providing a secure grip, and the cap system has a locking mechanism that prevents spills, which is a lifesaver during busy snack times or outings. For cleaning these tumblers they go straight in the dishwasher and come out looking like new. Overall, I highly recommend the Zak 2-pack tumbler for toddlers. They combine functionality, fun designs, and ease of cleaning, making them a perfect choice for any parent!

Adorable two pack kids water bottles. I love the stainless steel inside, and easy detach straw for cleaning components. The cap release lock is nice to prevent it from opening when dropped and keep from spilling.

This two pack of kids sport bottles. Are very durable. The kick feature in the flip open lid is a smart idea. Prevents spills ! The designs are super fun and the kids were excited to pick which one would be theirs. Keeps their water cold all day while at school. However, the only thing that our 5 year old complained about is that it is hard to drink. He isn’t used to using a straw like cup. More the open mouth pour type bottle. Worth the money!

Daughter absolutely loves the designs! She wanted to switch to one of these water bottles as soon as it arrived. They are built well and the lock and button mechanism work well and feel sturdy! The only issue is that the handle pops out of its socket pretty easily, my daughter was frustrated because it was stuck and not working right due to this but I popped it right back in and it’s an easy fix (not actually broken, just out of the socket). I docked it one star for that, otherwise they are great!

The bottles seem okay, hard to open, but they are bit durable, and portable. My daughters love them because they look fancy and stylish. Well coated inside and ice lasts for quite some time. Overall decent product. Good enough for kids school time.

I was very excited to try these new Zak Bottles, as other models have been a hit in my house with my six-year-old son. He loved the designs and the mechanics of the bottle; he simply could not stop closing and opening the lid while also playing with the locking tab. These bottles came in very handy this last Halloween to keep him hydrated while he collected all kinds of treats from our neighbors. The reason for my 3-star review is how hard the button and locking slider were to use, my son needed to use his teeth to move the tab from lock to unlock and the button in my opinion requires too much force to pop the lid. We have other Zak bottles and these seem to be easier for young kids, and maybe with additional use both the locking slider and button will loosen up more.

These water bottles have a cute design for children. They open with a push of a button and there is a lock feature to prevent leakage of water. They keep the water cold for a good period of time and the interior is antibacterial. My 5 year old son had difficulty drinking through the straw. He had to use a tremendous amount of sucking force to get the water out. This is a problematic feature because it prevented my son from drinking water at school because it took too much energy to get the water out.
