I've had Stanley vacuum bottles for years. A few years back I bought the 24 oz. one to take cans of soup for lunch in the winter time. A hot lunch for about $1.50 is good for me as I work outside in the weather. A while back my bottle quit keeping the soup hot so I called the # on the bottom of the bottle and they sent me a new stopper gasket. I tried the bottle with the new gasket and it still did not keep the soup hot. I called Stanley again and told them and they are now sending me a new bottle free of charge. you gotta like companies that stand behind their products!
