I replaced the original Trangia 27 aluminum boiler with this one. Works better. Food does not burn so easily to the bottom and easier to clean. Of course, you have to be more careful with the coating than with a regular aluminum boiler.
A good accessory to the basic trang, I replaced this with another standard aluminum boiler, with this it is more comfortable to make a fit directly with the trang, while the second boiler can still be used directly by the campfire for washing water / snow melting
Great pots. Once you have used these, you don't want to touch aluminum boilers anymore!
