Good quality

good product, a little better for keeping the cold cold, but doesn`t work very well with hot drinks

Good but hotness is reduced hour to hour

very baaad it haven’t complete a month and it’s spoiled already !! water dont stay hot and starting to have rusk

Not homding heat.very bad quality product

24 hr hot water capacity. Very good

This was really useful for my aged parents when they prefer to take warm water to places. It would hold the water warm for a good 4-5 hours. There's no leak. Like the cup feature in its cap. Makes it useful on the go.

Honestly what a flask, it kept a tea warm even after a full day of work and left in van got it next morning to clean as forgot it was still warm! Obviously not hot but warm enough to drink after 24h

Good product

I'm a bit of a skeptic when it comes to those '24-hour' claims, but I figured, why not? My old flask was basically just a fancy cup at this point. I can tell it's made of good quality stainless steel. It's got a nice weight to it, not flimsy at all. The plain lid is simple, which I actually prefer. No fancy gimmicks, just a good, tight seal. And let me tell you, that seal works. I've tossed it in my bag, shoved it in my car, and not a single drop has leaked. Huge win! Now, for the real test: The temperature. I filled it with piping hot coffee around 7 AM one morning. By lunchtime, I was expecting it to be lukewarm at best. But nope! Still steaming. I was genuinely surprised. Then, just to see how far it would go, I left a bit in there until late afternoon. Guess what? Still hot, though admittedly not scalding. It was more than drinkable though. Then I tried it with ice water on a hot day. I filled it up in the morning, left it in my car while I ran errands, and by the afternoon, it was still refreshingly cold. Not just cool, but cold. That's pretty impressive.
