I took this handy cooker and some extra "bricks" with us on a days fishing on the beach in Ayrshire. I dug a pit roughly 2ft x 2ft and 1 ft deep level at the bottom. Centering the cooker in the hole with 4 hex brickettes i was able to boil 2 litres of water in 5 minutes, enough for 4 pot noodles and some cups of tea.The design of the cooker allows for safe transporting and fast placing for when you need it. I found that i could pick up the cooker only 5 minutes after i had finished the cubes off. I now make sure ive got cooker and fuel with me every time im going out for the day.
