I cringed at the price but after seeing some of my friends go through sippy cup after sippy cup and hating them all, I decided to bite the bullet and get the grosmimi ones. A few cons but So far we love them! PRO: - - high quality medical grade PPSU. We had to replace multiple baby bottles because of scratches and PPSU is so much sturdier. Great because our 12 month old now flings his cup across the room - control flow nipple for our son who would constantly choke on traditional straws. Now he doesn’t. - easy to clean - easy for him to hold - fits our pigeon nipples - interchangeable tops. Got the flip top for travel. - truly rarely rarely leaks despite constantly being dropped - it spins so I can pivot the cup so the straw reaches his milk/water in whatever position he holds it in. cons: - expensive and lvl 1 nipples need replacement quickly. Ours have never tore but after 1 months you will see the integrity starting to crack. Lvl 2 is way sturdier and going strong for a month now. - it DOES leak (but rarely) if milk is stuck in the straw and the cup is thrown/dropped… but only a few drops. Review: Good toddler sippy cups - I purchased the Sippy Cup my toddler in January, and after a few months of use, I can confidently say it’s been a fantastic investment. While it’s on the more expensive side for toddler sippy cups, the quality and functionality make it well worth the price. The soft silicone straw is gentle on my toddler’s gums, perfect for transitioning from a bottle. The rotating handle, which isn’t fixed or screwed to the cup, makes it incredibly easy to adjust the cup’s position so my toddler can drink every last drop. The spill-proof design truly delivers, preventing messes even when the cup is tossed around. It’s lightweight and easy to clean. This cup has become a staple in our daily routine, and I highly recommend it! ## Features - SPILL-PROOF FROM FIRST SIP — NO MESS, NO STRESS: Designed for babies beginning their cup journey at 6+ months. The spill-proof +Cut straw and flip-top lid help prevent leaks when your little one tips, drops, or carries the cup. Built for the messy moments of learning to drink—without the mess. - SAFE FROM THE INSIDE OUT — PREMIUM PPSU + SILICONE: Every part that touches your baby's drink is made from premium PPSU or food-grade silicone. No metal or microplastics in the drinking path—just thoughtfully selected materials designed for everyday feeding and drinking. - EASY TO CLEAN — TOP-RACK DISHWASHER, MICROWAVE & STERILIZER SAFE: All parts fully disassemble for thorough cleaning. Top-rack dishwasher safe, microwave safe, and safe for boiling or steam sterilization. Durable PPSU and silicone are designed to withstand repeated cleaning and daily use. - TWO STRAW STAGES — SAME SEAL, DIFFERENT BITE: Both stages share the same leak-proof cross-cut straw and flow rate — only the firmness differs. Stage 1 (6M+) is soft for new gums and first sips; Stage 2 (12M+) is firmer to resist biting. Start with Stage 1, upgrade when chewing begins. - 360° ROTATING HANDLES — EASY GRIP, EVERY LAST DROP: Soft handles rotate a full 360° to follow your baby's hands — no awkward wrist twisting. They tilt with the cup, so your little one can drink down to the very last drop. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08398KZ2B | | Age Range Description | Baby, Toddler | | Best Sellers Rank | #722 in Baby ( See Top 100 in Baby ) #23 in Toddler Cups | | Brand | GROSMIMI | | Brand Name | GROSMIMI | | Capacity | 6 fluid ounces | | Color | Beige | | Customer Reviews | 4.5 out of 5 stars 3,705 Reviews | | Finish Types | Glossy | | Included Components | Cups | | Item Dimensions W x H | 3.9"W x 5.7"H | | Item Weight | 97 g | | Manufacturer Part Number | 1001-CB | | Material | Polyphenylsulfone (PPSU) | | Material Features | Insulated | | Material Type | Polyphenylsulfone (PPSU) | | Material Type Free | BPA Free | | Model Number | 1001-CB | | Number of Items | 6 | | Occasion | Everyday | | Other Special Features of the Product | Dishwasher Safe, Spill Proof | | Pattern | Solid | | Product Care Instructions | Hand Wash Only, Microwave Safe | | Product Style | Tableware | | Recommended Uses For Product | Home | | Reusability | Reusable | | Shape | Round | | Size | 1 Count (Pack of 1) | | Special Feature | Dishwasher Safe, Spill Proof | | Style | Tableware | | Theme | Baby | | Unit Count | 1 Count | ## Product Details - **Brand:** GROSMIMI - **Capacity:** 6 Fluid ounces - **Color:** Beige - **Material:** Polyphenylsulfone (PPSU) - **Special Feature:** BPA Free ## Images ![PPSU Baby Straw Cup Stage 1, 6M+, Spill-Proof, 6oz (Beige) | Babies & Toddlers 6+ Months | Removable Rotating Handles | Silicone Straw | Heat-Resistant | BPA-Free Sippy Cup | 200ml - Image 1](https://m.media-amazon.com/images/I/51AeEGb6s3L.jpg) ## Available Options This product comes in different **Color** options. ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ The best sippy *by J***E on March 10, 2024* This cup was HIGHLY recommended.
