Great cup
Our go to cup for my 2.5 year old. She got it last Christmas and luckily I filled it before she got it as she wanted to drink out of it straight away. Great to find one that isn't all plastic. Easy to clean compared to other straw cups so that mould doesn't start growing.

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

This straw cup has been great for my daughter! It’s easy for her to use, sturdy, and most importantly—it doesn’t leak at all. We’ve tossed it in the diaper bag and had it tip over plenty of times with no mess. Definitely a reliable, everyday cup and one I’d happily buy again and I have. We own 4 of these

Bought this for my grandson when he is over. He loves the design and it was leak proof the whole visit. Kept the drink cold on our visit to the zoo.

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

Gets moldy very quickly if it is not cleaned consistently. Great for traveling. Fit in diaper bag side pocket and car seat cup holder. Color was accurate. The imaging faded very quickly though. We always hand washed and never put it in the dishwasher so that kind of surprised me. It did well keeping things cold though.
