[This review was collected as part of a promotion.] First impression these are very cute cups and they are quality made. My kids love there new cups! One is plastic and the other is stainless steel. The stainless steel cup keeps drinks cold for a long time.The plastic one not as long but depending on the child the plastic may be better for them. They come in such cute designs. If the cups turn over they don't spill although a couple of drops may come out of the straw but that's it. I like that it also came with a replacement straw in case you need it. They are the perfect size for kids holds just the right amount and easy for them to hold. If you have kids I would recommend these Zak cups.

[This review was collected as part of a promotion.] My kids love these cups! Fun design and easy to hold. They wash well and fit in a cup holder. They also don’t spill, which is a huge parent plus! My kids see it as a “big kid” cup because of the straw but I don’t have to worry about spilling! Will purchase more!

[This review was collected as part of a promotion.] This set has been great for my little toddler. Very durable and leak proof. The vacuum sealed stainless steel one is great to keep his little drinks cold. And he loves using the straw. He has dropped them both multiple times and have had no issues, very easy to clean as well

[This review was collected as part of a promotion.] I love these cups they are soooo cute and my daughters love them. They straw tumblers that leak proof. Which is great because when you have little children accidents are prone to happen. I give this cup a thumbs up!

[This review was collected as part of a promotion.] Received this product through influenster inexchange for my honest review, and these cups are super cool. My girls loved them, and they used them daily. The thermo cup keeps the water really cold, and the plastic cup is a good daily drinking cup. It also came with an extra straw in case the others get damaged. They are dishwasher safe, but if you want to play it safe, handwash is good as well. Overall, this product works really well, and the kids love it!

I bought these cups because we love to use stainless steel when we can and the dinosaurs were soo cute. Although the design did eventually start to run off:( but it still does it's job!

Overall pretty good, but the straws seem to always be an issue for us. We've lost a few cups to the straws breaking.

[This review was collected as part of a promotion.] The Zak design Kelso straw tumbler stainless steel and plastic cups are really cute design that my daughter instantly loves and was excited to try. The cups are fun and great size, but they can be difficult to drink from for the child if the straw isn’t pushed firmly all the way into the cup.

[This review was collected as part of a promotion.] I received this product in exchange for an honest review. My five year old loves this cup! Perfect for on the go. I don’t love the way the straws go together- a little tricky to get in and adjusted just right. New favorite.

I received this order on 8/7/23, after after only about 2 weeks, both of the plastic lids are cracked. I wanted to like these, but I’m pretty upset the lids cracked so quickly. The cups themselves are very cute and I like that the straws can’t be taken out by kiddos.
