Review on 💼 KoKoBin Vacuum Insulated Tumbler Travel Mug: Triple Wall Stainless Steel Coffee Thermos, Keeps Hot & Cold for Hours (51 OZ/1.5L) Black by Dedra Block

So yes, it's a thermos. But the photos don't show very well the very poorly designed handle (rubberized plastic that bulges outward to be usable rather than a hinge design) and strap. I don't like the exterior design, it feels too chunky and the integrated plastic mouthpiece doesn't feel like something that really lasts (very fragile). The metal inside is painted (not used, it's just poorly polished), it's not dishwasher safe and the instructions are all in Chinese so I had to use a translation app to get the gist (some things still are a mystery if you take the word literally). Translation). This raised concerns about safety, durability and cleanliness. I'm glad I bought it just for emergencies. I wouldn't think it would work.
