CURATEIQ

TrustScore breakdown

89 /100

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

Tableware Material Safety 91

The tumbler body is named as 304 stainless steel outside and 316 stainless steel inside, an undecorated food-grade metal construction with no bamboo or composite material involved, and it is electropolished without residual polishing compounds.

Decoration & Coating Risk 79

The food-contact interior is SUS 316 stainless steel rather than a coated surface, but the tumbler's exterior carries printed designs such as Cherry Peach, Unicorn and Dino Khaki, and no lead or heavy-metal testing of that print is published.

Food-Contact Material Safety 85

The drinking tip is disclosed as silicone and BPA-free, and the body is named 304/316 stainless steel, but no bisphenol (BPS/BPF) or phthalate statement is published for the silicone tip itself, only a bare BPA-free claim.

Heat & Dishwasher Guidance 91

Care guidance explicitly bars microwave and oven use rather than promoting it, and gives per-part sterilization compatibility along with a concrete 2-3 month silicone-parts replacement interval and scratch-prevention advice using a soft brush.

Heat & Wear Behavior 91

The care guide gives a concrete replacement interval for silicone parts (every 2-3 months) and explicit sterilization compatibility per component — hot water, UV, dishwasher and steam all specified, with microwave use explicitly excluded rather than marketed.

Recall History 97

We queried the complete CPSC recall database directly — 10,027 records spanning 1973 to 2026, with a control confirming the corpus covers comparable product classes like toys and pacifiers — and found no recall filed against this brand in any role.

Certification Credibility 87

The brand's NSF-certified, FDA-compliant material claim and a third party's LFGB heavy-metal test citation both attach to PPSU feeding bottles and straw cups, not to this stainless-steel tumbler, whose disclosed materials are SUS 304/316 steel, BPA-free plastic, silicone and TPE with no independent or brand certification named for those materials.

Transparency & Support 91

Materials are fully itemized by component (SUS 316/304 body, BPA-free plastic cap and ring, silicone tip, TPE strap), country of manufacture is disclosed as Korea, and the brand publishes a concrete 1-year warranty against manufacturing defects and leaks with no-questions-asked replacement.

Customer Stories

Sentiment Summary

Customers frequently praise how easy the cup is for small hands to hold and use independently.
Many reviewers mention that all parts come apart easily for thorough, mold-free cleaning.
Several customers say the cup holds up well to repeated drops and rough toddler use without breaking.
Customers say the design helps prevent spills and leaks during everyday use.
Some customers feel the cup is worth the price given its durability and design, while others note it is on the expensive side.

Absolutely love this tumbler! The quality is amazing, easy for little hands to hold, and it keeps milk fresh for a long time. My daughter now drinks her milk only from this bottle 😊 Highly recommend for toddlers!
Helen K.
I got this cup for my 5 year old to replace his Owala tumbler that always leaks and spills all over his backpack. He loves it! It’s easy to drink from and does not spill
BriAnn B.
I like there is a silicone bottle to protect the bottom of the bottle
