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, itโs 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 childโs cup is fully washed and sanitized. Iโve 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.

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 doesnโt immediately spill everywhere.

Cute but not for small kids
I love the Eric collaboration print and it even looks more vibrant in person. The shape is slim and friendly to small hands. BUT, as the target audience is for small kids, the straw it way too easy to be pulled off and the water easily leak out like small falls. I would love to keep it but the cup defeats the purpose.

Straw pops out easily
The straw pops out of the lid too easily and 5 pieces is pushing it for how many pieces to deal with and keep together. Other than that it's great and our kid loves it for smoothies. We were tired of him tipping over his smoothie so this cup avoids the sticky mess. Keeps it cold too. $25 is steep but seems companies get away with whatever.

Must-have straw thermos flask for babies/toddlers
One of our baby/toddler must-haves! It doesnโt leak when baby accidentally drops it on the floor. However, liquid does come out if the straw is flicked. Overall, this is a great straw cup/flask for a baby learning to drink from a straw. The straw is soft and flexible!

Cute and quality
Great quality, the same feel as my hydroflask but in a cute kids size! Love the colour. My kid loved the novelty of it for about 2 days then unfortunately wanted her old sippy bottle back. I don't know why! I like this.
