Love it!

Just got these cups for my daughter who is obsessed with bluey! So far it's held up to not leaking, which is a must with littles!

Great cups

My son loves this cup but you should also sell extra straws.. I had to buy a new set because my son loses his straw but they are great

Worth the money

My daughters enjoy these cups and get used a lot. Also, easy to clean and reuse right away as long as you're using it with water only.

The best

My little one started using these cups at 10 months. They are great for travel, easy to clean and an item I would highly recommend!

Great until they aren't

These cups are great. Unfortunately after only a week, one of my valves is leaking and the cups/ characters are already scratched.

leaky cups

We have had these a month or so and the started out fine until they didn’t. The now leak no matter what we do. It is quite frustrating and we are about to just throw em out. Waste of money.

Great Kids Cup

Great cups no issues would say 5 stars but the metal dents easily and when my pre schooler gets on the sand pit the cups get sand particles caught in the lid and straw. Apart from that I have no issues with the cup.

Zac Shark Cup

My 2yr old Grandson cup straw is broke…I took cup away from him because I was afraid he might bite the rest of the straw off and swallow it… Will not buy again…

Pretty but...

They leak! Which is number one criteria for a toddler cup. They leak from the seal ring when tipped over for drinking. It's so annoying. 2 stars only because they are adorable and sturdy. But leaky

Excellent product

These tumblers are amazing. Because of the double wall insulation, cold beverages (milk) at preschool stays fresh all day, even during the heat of the summer.
