Zak Designs Kids Durable Plastic Spout Cover and Built-in Carrying Loop, Leak-Proof Water Design for Travel, (16oz, 2pc Set), Marvel Avengers

These are just right. Just the right size for school, not heavy but still of good quality. Don’t break when reasonably handled ( my 6yo isn’t particularly gentle but not rough either). Easy to clean

These are great because they're easy to clean, and really don't leak. My son has already managed to break off one of the red spout covers though so they aren't super durable against 5yr olds. The upside is even without the red part it really doesn't leak very much at all

Great cups and good doublePack deal

I was really disappointed with these! I only buy Zak bottles for my kids because they have the best designs and the flow of liquid is good. Upon pressing that button to open up the lid, it barely pops up a bit and you have to lift it up with your fingers which is still fine but you also have to touch the spout to open it up which is so unhygienic! Both bottles have the same issue

I like the locking mechanism- easy for my 4 year old to master. He loves the Avengers design. I don’t know yet how long they’ll hold up, but for a 2-pack, you’ll definitely get more longevity than with a single for the same price.

My son cracked both of these within a week or two of getting them. I didn’t really see him throwing it or anything like that the cracks seem to be from just normal wear and tear.

Not leak proof. That was the whole purpose of this purchase. If the straw is open and able to drink out of, it leaks. Even if it’s closed/locked, it still leaks. Even just slightly tilted, it leaks all over my kids’ shirts. The other style of this cup does not leak. I will just buy more of them. You don’t need to advertise that it’s leak proof if it isn’t. That’s why parents buy things like this-bc it is advertised as something they NEED to make life easier. You’re making it harder on us when we buy a leak proof cup that leaks everywhere all over everything.
