BEST PURCHASE AS A MOM
Love this cup! My son started using it at 10 months old. (I did teach him how to use a straw with one of those bear cups). We’ve had this cup for 6 months now, still has not once leaked (other than the little droplets left in the tip of the straw), keeps things cold, has kept milk warm, my son started holding it on his own right away. I through it loose in my bag and never worry about leaking, I give it to him in the car and never worries about spills. Love that it’s stainless steel and silicone, the only plastic is the lid. I literally tell every mom to get this cup.

Awesome cup!
Highly recommend this cup especially if you have a toddler! Very spill free and easy for them to use and drink from. Keeps the water or juice fresh and cold. Also I love how they have different designs. Worth buying.

Great at not leaking
This cup is a great size and doesn't leak, which is super important. The straw is a little hard for my 10 month old to manage because of the leak proofing function. He's probably just too young for this cup, but he loves straw cups and my nephew has this one and enjoys it so I thought I would give it a try. I will keep trying it with him as I'm sure he'll get used to the straw.

Already love this cup!
I've been the owner of this cup for about an hour and I already LOVE it! My kiddo loves to tip his cups as if they're bottles when he drinks so I just took off the inside straw and it still functions perfectly. He's able to drink from it easily without spilling his milk everywhere. I love that its so easy to assemble/disassemble for easy cleaning and that its leak-proof and insulated to keep drinks cool. Highly recommend this cup! However, I do have to mention that the valve does require strong suction to drink, so I would ONLY recommend this for kiddos 2+ year's old who've already learned how to drink from straw cups properly.

Great product
I absolutely love the Zak Designs Kelso Toddler Cups! My baby started using it at 9 months old, and it's been a hit ever since. She loves it, and I couldn’t be happier with the design and durability. Stainless steel is also simply a much better alternative to plastic. It's also super easy to clean. Highly recommend this cup for anyone looking for a safe, practical, and stylish option for their little one!

Don’t drop on ground.
Great cup but don’t drop it on concrete. My son dropped his on concrete and he is 2. So not a very far drop. A piece of something inside the walls of the cup is now rattling around. Still able to use.
