I've bought 2 different sets of this brand and both times one leaks. It leaks out the side of the lid.

These cups are great. Unfortunately after only a week, one of my valves is leaking and the cups/ characters are already scratched.

My 2yr old Grandson cup straw is broke…I took cup away from him because I was afraid he might bite the rest of the straw off and swallow it… Will not buy again…

We have had these a month or so and the started out fine until they didn’t. The now leak no matter what we do. It is quite frustrating and we are about to just throw em out. Waste of money.

They leak! Which is number one criteria for a toddler cup. They leak from the seal ring when tipped over for drinking. It's so annoying. 2 stars only because they are adorable and sturdy. But leaky

[This review was collected as part of a promotion.] I will never buy another cup after this purchase! My son would agree that no other cup holds a chance compared to the durability and quality of Zaks brand. We highly encourage your products Zakaria. Thank you for your commitment to service.

[This review was collected as part of a promotion.] These cups are the best. My kids are hard on their cups and these can take a beating. As a busy mom, I especially love how easy they are to clean--the straw part easily pops out and can be soaked in a bowl of hot, soapy water and the stainless cups I can pop in the dishwasher. No leaks so far! We plan to buy more!

[This review was collected as part of a promotion.] I got these cute cups because they had Yoda on them with a straw. My 6 year old grandson always wanted to take his drink with him in the bedroom so he could play his games. I dreaded hearing "can I have a paper towel " because I knew that meant he had spilled something. Since I got these two tumblers I don't have to worry about the spills, or leaks, and keeping the 12 Oz. cold or hot. We are both happy !

[This review was collected as part of a promotion.] Great cup only one flaw because of the straw it will leak if upside down. My daughter loves the designs and I love the sturdiness of the cup. Thankfully my daughter is at an age she doesnr spill often or turn her cup upside down. Overall very nice cups.

Tight locking Lance was good study quality keeps my kids happy! These cute little Disney cups are now a must have for our family when we hit the car. Tight locking Lance was good study quality keeps my kids happy! The thermal lining in them keeps cold things cold and hot things hot which is ideal when you have a toddler in the backseat. I would highly recommend this product for anybody who has a littles in the car that are constantly taking lids and stuff off.
