Plain Lid 500 Thermosteel 24 Hours Hot and Cold Water Bottle, 1 Piece, 500 ml, Silver | Leak Proof | Office Bottle | Gym Bottle | Home | Kitchen | Hiking | Trekking | Travel Bottle

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.

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.

24 hr hot water capacity. Very good

Good quality

Excellent

Although this flask is well made and packaged nicely, it doesn't live up to expectations and doesn't keep hot drinks warm enough. I never expected it to stay warm for the advertised 24 hours and 5-6 hrs would have been fine, but black coffee was just luke warm after 4 hours. Not sure about keeping things cold as never tested. Sorry but I had to return

Great product—seals tightly and maintains the temperature effectively.
