Fantastic Toddler Cup – Durable, Leak-Proof, and Adorable!
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!

Leaves a little bit of drink in top of straw
Easy to clean and non toxic etc but when we use it for smoothies the liquid gets stuck above the valve and easy makes a mess if dropped etc

Hard to suck out of.
Didn't like this cup at all for toddler. It's too hard to such through the straw, even as an adult.

Damaged lid
The cup was delivered yesterday and the lid has a large crack around the threads so the cup can’t be used
