GREAT CUPS

[This review was collected as part of a promotion.] These are nice stainless steel cups that come with a straw that are great for traveling with kids. My grandson likes star wars so I picked up that one which comes in a set of two. These cups are 12 ounces which is perfect for kids and since they are stainless steel they actually keeps the drink cold. Very satisfied with these so if you have kids give them a try.

Sturdy cup

[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.

New favorite in our home!

[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.

Easy Cleaning

[This review was collected as part of a promotion.] I got these tumblers to try. I wanted to see how effective the straws were in staying clean. I cleaned them with each use. The straws never built up any residue in the straws. The lids stayed clean around the rim. Even when they got tipped over, it rarely spilled over. Overall, it was a time saver with cleaning it and cleaning after my little one.

Love these

[This review was collected as part of a promotion.] I love these stainless steel cups. The Disney Princess prints that we have are so cute. The stainless steel keeps the drink cold longer than your typical plastic cup. The straw comes apart so it’s easy to keep clean. So far there haven’t been any spills either!

We love these cups!

[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!

Worst cup I ever bought

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

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.
