Review: My son's favorite bottle, but the straw broke after three months. - To be fair, can't say the quality of the straw is bad, my son is keen on flipping back and forth with the straw in his mouth. That power is not small. Three months later, the hole in the straw was getting bigger and bigger, and I was worried that one day he would swallow it if it's suddenly broken, so I had to cut off the broken part. But the shortened straw was too short and he never used it again after that. We have another green one, and this one has survived, that's why I still give 4 stars.
Review: Best ever - My baby loves using the bottle!

## Questions & Answers

**Q: What is PPSU, and why is it better than standard plastic?**
A: PPSU is a premium material used in hospitals commonly used for medical devices. Unlike standard PP plastic, it has extreme heat resistance, resists scratches to prevent bacterial growth, and will never warp, stain, or leach microplastics.

**Q: My cup is leaking from the straw. How do I fix it?**
A: Check if the cross-cut (+) valve is torn. If it is intact, simply pinch the air valve on the silicone base 3–4 times after closing the lid. This equalizes internal pressure (especially from warm drinks) and instantly stops backflow.

**Q: What is the difference between Stage 1 and Stage 2 straws?**
A: They share the same leak-proof valve and flow rate. Stage 1 is ultra-soft for sensitive baby gums. Stage 2 uses firmer, high-density silicone built to withstand biting and chewing from older toddlers.

**Q: Is the cup dishwasher safe? Which rack should I use?**
A: Yes, it is top-rack dishwasher safe. Keep all parts away from the bottom heating element to protect the materials.

**Q: How do I wash the silicone straw without tearing it?**
A: Separate the straw nipple from the tube. Insert your straw brush gently, and twist it side-to-side to clean. Never scrub the brush up and down vertically, as this may puncture the cross-cut valve and cause leaks.

### ⭐⭐⭐⭐ My son's favorite bottle, but the straw broke after three months.
*by K***N on 15 March 2022*

To be fair, can't say the quality of the straw is bad, my son is keen on flipping back and forth with the straw in his mouth. That power is not small. Three months later, the hole in the straw was getting bigger and bigger, and I was worried that one day he would swallow it if it's suddenly broken, so I had to cut off the broken part.

I bought the GROSMIMI Spill Proof Sippy Cup with high hopes of a leak-free, fun experience for my toddler. Let me tell you, it was a disaster on every level. Here's why this cup deserves a big, fat 1-star rating: Leak City: This cup is anything but spill-proof. It's like a leaky faucet disguised as a sippy cup. Every tilt, every giggle, every accidental bump sends liquid cascading out the sides, the straw, anywhere it can find an escape. Forget diaper changes, you'll be needing outfit changes every five minutes. Straw Struggles: My poor kid sucked and sucked, but barely a drop of liquid emerged. The one-way valve seems more intent on blocking the flow than facilitating it. It's like trying to drink a milkshake through a clogged straw – pure frustration for tiny taste buds. Cleaning Catastrophe: Disassembling this cup for cleaning is like solving a Rubik's Cube blindfolded. Tiny parts, nooks and crannies galore – it's enough to make you want to throw the whole thing in the dishwasher (which, by the way, it's not safe for). Handle Heartbreak: The removable handles seem like a good idea in theory, but in practice, they're more trouble than they're worth. They pop off with the slightest tug, sending the cup plummeting to the floor (and shattering your hopes of a peaceful meal). The only "pro" I can find for this cup is that it looks sleek and modern. But that's about it. In terms of functionality and ease of use, it's an epic fail. My advice? Save your money and your sanity. Skip the GROSMIMI Spill Proof Sippy Cup and invest in something that works (and doesn't drive you to the brink of meltdown). Overall rating: 1 star (and that's only because I can't give it zero). P.S. If you're looking for a truly leakproof, easy-to-clean, and toddler-approved sippy cup, I highly recommend the Munchkin Miracle 360 Cup. It's a lifesaver, trust me!
