Hello There, I bought this Esbit thermos 0.5L and have to say that your money is really worth. The Esbit really sends a lot and staying tacky. Has 2 cups and is very stable. What really is the hammer, that's even after more than 8 hours, the water still is almost boiling hot and after more than 24 hours is still nice and warm just hammer. There is also the the Esbit from outside not at all hot is / is when Boiling water is in it. So I can really recommend the Esbit each. Just Awesome THANKS
