Worst cup I ever bought

Leaks all the time - the kids don’t even want to use them anymore.

Definitely Leaky

Cute and seem to be durable but they leak if tipped over. I bought these specifically because theyre supposed to not leak.

Leak worse than any cup I've owned

I was excited about these cups as I've loved other products from this company but these leak horribly. I wish I could return them.

Nice tumbler for kids!

Nice tumbler! I was disappointed that I received the Disney princess instead of the Bluey that I ordered. Other than that, it's a really nice tumbler.

wouldn't recommend

cute and can keep drinks cold quite a while but straw leaks if tipped over and sometimes when moving it while it's upright. Big fan of zak products but let down by these.

My child recieved this as a birthday gift. I thought yay a cup he can take to bed and not spill. WRONG. The cup leaked and soaked his bed. Not satisfied with this cup.

Hello from the Zak Consumer Care Team,<br /><br />Thank you for your review. We apologize for the challenge you have had with your Zak product. The spout has a valve for releasing liquid, if the spout is bent it can release liquid.

Perfect cup

[This review was collected as part of a promotion.] My son loves his new cup. It is very easy to clean. I would reccomend this for any toddlers. My son also loves baby Yoda. Keeps his drink nice and cold.
