Will boil water faster than you can put a chuck of chocolate in your mug, it will shock you! Well built, high quality. Keep in mind it is not for cooking just boiling I only put water in it. Has never let me down there are other brands that seem similar but don't be fooled they do not compare. Get this thing I recommend also getting a titanium spork to go with it. Ps it can hold that larger fuel canister if you do a little Tetris.
