CURATEIQ

TrustScore breakdown

92 /100

We take what's most important for a product to determine the TrustScore. Here's our research:

Bottle Material Inertness 95

The body is 304 stainless steel outside and 316 stainless steel inside, and third-party XRF testing verified the inner body as 316 stainless steel.

Food-Contact Material Safety 95

Third-party lab testing of Grosmimi's straw cups, including this 6oz stainless steel flip-top straw cup, found BPA not detected in any part, restricted phthalates and lead below reporting limits, and the polypropylene parts and silicone straw passing FDA food-contact requirements.

Decoration Lead Risk 77

This stainless cup is sold in printed designs such as Cherry Peach, Dino Khaki and Unicorn, and the brand's lead-free statements cover the sealing silicone, not the exterior print.

Heat & Wear Behavior 85

The silicone straw and teat should be replaced every 2-3 months and sterilization guidance is provided (30 seconds boiling before first use), but no test method or shedding/migration result at use temperature backs this interval, and the cup itself is explicitly marked not microwaveable rather than microwave-safe.

Nipple Material Safety 95

The platinum silicone straw passed third-party lab testing for volatile N-nitrosamines under FDA guidance, below the 10 ppb limit, and also passed FDA food-contact requirements for silicone with no BPA detected.

Recall History 97

We queried the complete CPSC recall database (10,027 records, 1973-2026) for Grosmimi and found no recall at any date, in any role. A control search confirms the corpus covers comparable feeding-product classes, so this is a genuine clean result rather than a gap in the registry. Grosmimi also states it has never issued a product recall.

Replacement Guidance 91

The brand publishes a concrete replacement interval — every 2-3 months for silicone straw parts — and gives visible degradation signals to watch for (pull the teat in all directions, discard at first sign of damage or weakness), covering both the interval and the check.

Certification Credibility 95

Grosmimi supplied third-party lab test reports and children's product certificates for its straw cups, covering lead, restricted phthalates, BPA, FDA food-contact requirements, nitrosamines in the silicone straw and small parts after use-and-abuse testing, with every result within its limit.

Transparency & Support 91

The brand discloses the country of manufacture (Korea) with a stated consistent QA process across markets, and publishes a concrete 1-year warranty against manufacturing defects with no-questions-asked replacement for leaks or material degradation.

Customer Stories

Sentiment Summary

Many customers say the cup is spill-proof and easy for young children to drink from and grip on their own.
Reviewers frequently describe the cup as durable, surviving repeated drops and throws without breaking.
Several parents mention the cup is easy to take apart and clean.
A few customers mention the plastic lid cracked or the handle felt loose after months of use.
Some customers note the cup is pricey but feel it is worth it compared to cheaper cups that did not work for their child.

I really like this bottle for my 7 month old who is learning to use a straw. Baby is really into it, and the bottle is sturdy!
Jocelyn Y.
For me it was very important to get a stainless steel cup since we didn’t want to use plastic. These are so well made and they are beautiful. My baby loves them! Worth the price 100%!!
Val
My 10 month old baby loves this bottle. It doesn't leak and easy to clean. The only problem the plastic lid broke after a couple months of use. I tried to use glue on it but unfortunately it did not work and the replecament cap is not available in pistachio. I still recommend it because baby my baby can use it easily by himself.
