⭐⭐⭐⭐⭐ Emily Tran - Parent, Austin, TX
"I bought the Advanced Model of this thermal lunch box for my 8-year-old in September 2024, and it’s been a total game-changer. The 4 inner containers are perfect for packing a main, fruit, veggies, and a snack—no more messy mixing! The food stays warm until lunchtime, which the school staff confirmed. I love that it’s EPR France certified; as a health-conscious mom, that gives me peace of mind. Easy to clean, too—just a quick wipe or dishwasher cycle."Purchase Date: September 2024 | Usage Period: 6 months
⭐⭐⭐⭐⭐ Daniel Park - Home Use, Portland, OR
"Switched from plastic to this 2.3L stainless steel lunch box in January 2025 after learning about BPA risks. The 4-layer insulation really works—my daughter’s soup was still hot 7 hours later on a field trip. The dark blue design is sleek and doesn’t look 'kiddie,' so she actually likes using it. We chose the Pro Model for its 5.2-hour insulation and premium hinge. Yes, it’s a bit heavier, but worth it for zero spills on the bus."Purchase Date: January 2025 | Usage Period: 4 months
⭐⭐⭐⭐☆ Maria Gonzalez - Daycare Provider, Chicago, IL
"We purchased 15 of the Base Models in November 2024 for our toddler meals. The stackable design saves so much fridge space, and the locking lids survive daily drops. Cleaning is simple—no trapped odors like with plastic. I wish the inner containers were dishwasher-safe on the top rack only, but that’s a small trade-off. Great for portion control and meeting hygiene standards. Will upgrade to the Advanced Model for older kids next year."Purchase Date: November 2024 | Usage Period: 5 months
⭐⭐⭐⭐⭐ James Reed - Outdoor Program Coordinator, Denver, CO
"Used the Pro Model during a winter camp in February 2025, and it performed flawlessly. Even in sub-40°F weather, hot pasta stayed warm for over 5 hours. The vacuum seal held through hiking and snowshoeing—zero leaks. I appreciate the REACH compliance for group meal safety. Durable enough for rough handling by teens. This is now our standard for all outdoor programs."Purchase Date: February 2025 | Usage Period: 3 months
⭐⭐⭐⭐☆ Sophie Lin - Meal Prepper, Seattle, WA
"As someone who preps lunches weekly, the customizable inner containers are a dream. I bought the Advanced Model in December 2024 and use it for both my kids and my own lunches. The ability to swap compartments means I can adjust portions for different days. Keeps cold salads crisp and grain bowls warm. Only downside? It takes up more backpack space than a soft lunch bag, but the performance makes up for it."Purchase Date: December 2024 | Usage Period: 5 months

"After going through three plastic boxes in a year, this stainless steel one is a revelation. Survived a 6-foot drop from a bus seat—barely a scratch. Food stayed hot, and my son says it’s 'cool' to open. Worth every penny."

"We use these in our classroom for snack time. Very durable and hygienic. Just a note: younger kids find the Pro Model a bit heavy. Base Model might be better for ages 3–5."
