My favorite cups for my toddler. Super easy to clean with only a few parts. The gabby dollhouse design and bright colors are something my little one loves. Light weight to throw in a bag for outings and has a good seal that rarely spills. Good price for two really good cups. My toddler finds it easy to drink out of the cup with milk water or juice. I don’t recommend for thicker drinks like smoothies functions well with thin liquids.

Love these cups for my two year old! He loves spidey and these were the perfect cups. They are spill proof. We had a very mild leak from milk that was left at the top of the straw. I feel like we got a good price for two cups.
StaceyReviewed in the United States on May 19, 2025
These are probably the best sippy cups I have bought for my toddler. I have about 5 of them and have not had one single leak. I will say that they do have to suck a little harder to get the liquid out. And since the straw is wider they will consume more faster but they get used to it pretty quickly. Do not sleep on the Zak Cups

These are extremely leak-proof in terms of tipping and dropping, but they leak as they warm up. If you put cold liquid in and let it warm up from ambient temperature, you'll eventually see water sitting on top of the lid. After time, it'll run down the side. I don't understand why this happens since it should be able to vent and equalize pressure. I call them micro-slits, but there may be another term for it. Either way, a micro-slit exists in the straw itself and on the lid in the rubber area next to the straw. This is how they made it leak-proof while still letting air in/out. Overall, we're very happy with these. Easy to assemble, disassemble, and clean. I like the large straw diameter for cleaning too. I'd give them a 4.5 out of 5.

These toddler cups have been a staple in our home, we mainly use them for milk, and they’ve worked out great. They’re the perfect size for little hands, super easy to clean, and have held up really well through daily use and countless dishwasher cycles. I also appreciate that they’re simple to assemble with no extra pieces to misplace. After heavy use, we’ve noticed a bit of leaking here and there, but it’s minimal and expected with the amount of wear they’ve had. Overall, they’re still our go-to cups and have made milk time much easier. Definitely a 5-star buy for any toddler household!

After this purchase, I’ve completely fallen in love with the Zak brand! These tumblers are not only super cute, but also functional and truly spill-proof—perfect for toddlers. I do recommend removing all parts when washing and hand washing the cups to help preserve the design, as it may wear off over time. Zak offers so many fun styles, and these cups really hold up well. Absolutely recommend!

Love these leak proof sippy cups for my almost 2 year old daughter who likes to throw the cups when she’s done lol. Love the princess on them. Easy for my toddler to use. I like you get two for a reasonable price. Definitely recommend.
Jarneshia BarberReviewed in the United States on May 18, 2025
Liked it however if your child is just learning to use straw type cups don't get these. My child would get frustrated and throw the cuz because he is used to tilting his other sippy cup upward,which caused this cup to crack. At first I thought the cup was leaking from the lid part but it kept leaking so after examination I saw that it cracked.im not blaming them because it didn't come cracked but like I said if your trying to get your child to drink from these without ever trying any other straw type cups with them then DO NOT GET THESE ,because if they get frustrated and throw it ,that's your money down the drain,I barely had this for a week😐.

I've tried a few different sippy cups with straws for my son and these are great. He throws them on the ground a lot and they don't leak (mostly, nothing is 100%). I also really don't like a lot of the silicone options, we had one sippy cup that had his water tasting like soap it was gross. These are easy to clean and toss in the dishwasher.

These are so cute, but my 1 1/2 year old has a hard time drinking with these. I think this should be for 2 years old and up. I am keeping them as they are great quality and my little one will use them soon.
