Review on 🦄 TEKKER's Insulated Thermos Food Jar Lunch Thermos - 17 Oz Stainless Steel Container for Kids, Vacuum Flask with Folding Spoon - Perfect for Office, Travel, Camping, Work, School, Outdoors - Pink Unicorn Theme by Kelly Starr

This is a low quality product that looks like the original but is not. The "stainless steel" cup is actually nickel-plated or something. Our TEKKER'S thermos arrived with tiny black marks on the mug/lid where the shiny material had chipped off. The threads of the screw caps are also not precisely cut. It's wrong. Every time you open or close the bottle, the cap gets stuck and you have to try multiple times. Last but not least, we could hardly open our bottle after the first use. The only explanation we could find was that we filled it with hot liquid. The liquid has cooled down. He created the vacuum seal. Almost impossible to break. By the way: When we washed the bottle, the cap fell off at the top. It's just stuffed with hand-cut styrofoam! (photo) After that we threw away our TEKKER'S. Conclusion: Looks like a cool thermos, but it's not very well made.
