Stays cold, and doesn't leak much
This is by far my favorite toddler cup. It stays cold basically all day as long as I put ice in it in the morning. it's easy for my toddler to use. My only complaint is that it's not 100% leak proof. If my toddler leaves it on the ground with the straw touching the floor, it will leak. Other than that it won't leak, but it also leaks the least out of almost every cup I've tried. Especially for an insulated cup. It is a little heavier than other toddler cups but that's to be expected, also my toddler gets mad she can't lay down and drink out of this so it is mostly an on the go cup. Doesn't work for nap time for us. But I would definitely recommend this cup to anyone wanting an insulated on the go cup.

The household toddler sippy cup.
Ok this is the cutest cup. Great price. No leakage. It keeps drinks cold and is easy to clean. You can order replacement parts - which I love cause my daughter chews on the end of the silicone straw piece. It holds a good amount of liquid and the lid screws on. Again, super easy to clean. I put the cup and lid in the dishwasher but I wash the silicone straw piece and the straw inside by hand - but I just use a straw cleaner for that and I am done in 10 seconds.

Leakproof and sturdy
Love this cup! Leakproof and my toddler has thrown in on the ground off her high chair multiple times and it hasn't broke very durable. Beverages stay cold ! Cleaning is easy also ! Would recommend and will buy more in the future.

LOVE THIS CUP!!
Favorite tumbler cup for my 1 year old! It keeps cold for hours up on hours, super functional and does not spill or leak. It’s very easy for my 1 year old to hold on her own and the design on this is so cute! We love the color and could not recommend it enough.

Best Toddler Cup!
This is by far the best cup I’ve tried. It’s great quality and comes apart easily to clean. It literally doesn’t leak, which is a huge plus. I can just throw it in my bag without worrying about it tipping over. My daughter is in a throwing stage so she’s thrown it quite a few times and there’s only a small chip so far (pictured). She started using it at 9 months but has been able to hold it herself with ease, even when it’s full of water and heavy. My only gripe is that I’m not a fan of the plastic straw attachment but I replaced it with a silicone smoothie straw and it has worked out great. Overall I definitely recommend this cup especially if you’re in search of something stainless steel & leak proof!

Strong Contender for a leak proof toddler cup
Ordered this for my 20 months and it was perfectly leak proof for a while. Put all the parts in the dishwasher and there is a very small piece that is not connected (covers a small straw spout option) that got lost in the dishwasher. Unfortunately this was very important to keep it leak proof, wish they had attached it somehow as to not get lost, but you live and learn. Still works fine, solid cup that keeps liquid cold, easy for small hands to hold, straw is easy to get the liquid out for little mouths. Just might want to wash the lid by hand only or remove the small piece to ensure you dont loose it.

Perfect cup
These are my favorite tumblers for my kiddo. The stainless steel doesn’t absorb scents of drinks and it keeps warm things warm and cold things cold. Easy to clean and definitely durable! It also fits in car seat, stroller, and high chair cupholders.

Easier than other non-spill options
This one is so much easier for my 13 month old to drink out of than other non-spill cups. They don’t have to bite or suck with as much force which is great for a younger toddler just learning after using straw cups.

Heb deze beker voor mijn nichtje cadeau gedaan. Ze was meteen verliefd op de beker. Het enige waar ik niet zo akkoord mee ben is dat er duidelijk staat LEKT NIET. Maar als je hem ondersteboven houd lekt hij wel degelijk

The Zak Designs Kelso Tumbler Toddler Cup is hands down one of the best sippy cups I've ever purchased for my little one! The 12oz size is perfect—just right for keeping drinks at the right temperature without being too heavy for tiny hands. The vacuum-insulated stainless steel design is impressive. It keeps my child’s drinks cold for hours, which is especially great for long car rides or days out. I also love that it's completely leak-proof. We've tried so many cups that promise no leaks but still end up with spills. This one actually delivers! Even when it gets tossed around or turned upside down, it stays sealed tight. The "Happy Fruit" design is adorable and colorful, which my toddler absolutely loves. The cup is also easy to clean, with no small parts that can trap dirt or mold. The durable stainless steel construction has held up well to all the drops and throws—it still looks as good as new after weeks of use. Overall, this sippy cup is a winner in my book. It’s durable, effective, and fun for kids. I highly recommend it to any parent looking for a reliable and cute cup for their little one!

Not even a year after having this the lid completely cracked to where it is no longer useable. With this being a toddler cup I would expect it to be a bit sturdier. I have 2 other cups like this from this same brand and they have held up to 2 years of hard use. It seems that this lid is a lot less durable than the cups I bought before.
