Love this
This is such a great cup for my little one. I love the silicone straw. Keeps drinks cold for a long time. Is NOT leakproof if turned on side/upside down, but I do not believe it is meant to be. It is great though bc if knocked over, it doesn’t immediately spill everywhere.

Easy to Clean + Hydro Flask Quality = Parent Win
My son was excited about this tumbler because he already loves the book and character, but what made me love it was how practical it is for everyday use. First, it’s by Hydro Flask, so it actually keeps drinks cold (and warm if needed) for hours, which is perfect for long days, school, or being on the go. What really stood out to me, though, is how EASY TO CLEAN. Every part comes apart easily, which makes a big difference when you want to make sure your child’s cup is fully washed and sanitized. I’ve used cups with hard-to-reach areas or pieces that are frustrating to put back together, and this is not that. For us, this was a win because it combines something fun for him with something functional for me. Definitely recommend for parents who want something easy to clean, long-lasting, and kid-approved.

Cute cup
I like this cup as it is good quality and simply out adorable. My baby girl is matching with mommy’s cup. I do have to say that it does spill easily which is annoying especially with young kids.

Okay
Great for younger kids in size but the whole straw unit pulls out through the top if they carry it around by the straw. We have had to clean up some messes.

Good insulation, but lid design needs work
Keeps drinks cold for hours and the size is perfect for kids’ hands. However, the lid tends to leak if the cup tips over or isn’t tightened just right. The stainless-steel build feels durable and easy to clean, yet the straw cap could use a better seal. Still useful for school lunches—just pack upright to avoid spills.

Great cup if you are looking for somethin smaller because it doesn't have a handle, has a straw.
Perfect water bottle if you don't want to carry something large. No handle, put in two ice cubes and the water will stay cold for hours. Love this cup
