Zak Designs Kelso Toddler Cups For Travel or At Home, 12oz Vacuum Insulated Stainless Steel Sippy Cup With Leak-Proof Design is Perfect For Kids (Fanciful Unicorn)

My daughter loves these cups, I prefer the insulated ones especially in the summer and for keeping milk from spoiling too quick. The only “leak” is if pressure builds it will occasionally bubble out the straw (this can happen to any cup that seals) but I have yet to see my 17 month old do anything that causes them to leak or spill and we’ve used Zaks since she was 11 months. The print has washed off on some of her plastic ones but the thermal cups have maintained their color/images perfectly. We have used them both with and without the straw (if I give her milk I leave the straw out bc she likes to turn the cup up to drink it instead of sucking through the straw). My favorite part is they’re the easiest I have found to clean, you can actually get to all the nooks and crannies!

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.

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.

This is my daughter’s favorite cup. It’s durable, but that also means it hits the floor hard when thrown or dropped. Easy to drink from, leakproof, and cute!

The absolute best toddler water/juice cup. It is actually leak proof. Most cups you have to close a lid or something that makes it leak proof, which is extremely frustrating for young toddlers. It’s also extremely durable.

Why did you pick this product vs others?:I love these stainless steel cups for my 1 year old. They don’t leak at all and he has no problem drinking out of them. However, after a few washes the designs start to peel off. Also, it’s super heavy so he has dropped it on his foot a few times :/

Bought this for my 2 year old as he always wanted to use his sister's cup (bigger size of same brand). This is the perfect size for him. We love the space design, and so far it has held up to lots of use and drops.

The toddler loves it. Perfect cup and worth the price. Super easy to clean and use. The seal is great and we have no issue with leaks. Anything carbonated will eventually push back up through the straw, so we use for “coffee”, water and juice.
