Review on Stanley Classic Vacuum Bottle 1.4L (Matte Black) - Superior Insulation for Long-lasting Hot or Cold Beverages by Dagmara Rudowska ᠌

I checked for the duration of storage of hot water, because. This is exactly what I expect from a thermos. Pre-doused with boiling water in order to heat the insides before testing. Immediately after boiling, I poured water from the kettle into a thermos, almost to the top, leaving less than 2 centimeters to the edge of the lid. Screwed it up tightly. Left at room temperature for 21 hours, from 20 to 17 hours. After opening the water temperature was about 50 degrees - it was hot, but the hand calmly endured. Therefore, there can be no talk of any 40 hours of hot water storage. Cooling mainly occurs through the neck, which is a "bridge" from the inside to the outside. I've been wanting to buy a Stanley for a long time after watching ads on YouTube a couple of years ago. Now disappointed. Since I didn’t have any thermos at all, this one will do, but with the same parameters you can pick up a thermos three times cheaper.
