I have just received, "Stanley Outdoor Vacuum Bottle 1.1 quart/946ml". The section about the product-related features explain, 24-hour hot / cold storage capability. And that is the reason why I preferred it. But it is not that explained. However, this statement is wrong and I regret to buy it. People who prefer this product have to know: 12 HOURS OF STORAGE CAPABILITY HOT / WARM STORAGE CAPABILITY 13-18 HOURS (enough to hold your finger in warm water).Thanks to Amazon for sending the product as soon as possible to Afghanistan than I thought.
