In reply to outdoorbloke:
I just got one, carry a lighter too as they do get damp. i make a litte tub of coffee, sugar and powdered milk all mixed together. and whatever anyone says a pot noodle or cup a soup is much better than cheese butties!!
The unit, a sigg full of water and food / brew stuff weighs the same as the steel flask and butties i used to carry, better if water is carried by two of you...
Gas is dear but the price to pay for a decent brew and hot meal?
Got mine for £44 from good old needle sports, very pleased with it.
