Neoaliphant, that is really weird. I have always thought the mess tins were massively under rated however the hex stove saw service all over the world and is often mentioned. I am sure someone, might have been Jocko, said something like the Brits are great however if you stop they will be making tea on those tiny stoves. Also I have seen pictures of them in use in the Falklands so if they worked there they should work anywhere. The UK, US, Australia and New Zealand all used them.
I have never had an issue with a Hex stove however I have had the Trangia wind issue which is a pain because you cannot see the flame or lack of it.
Lightweight hikers love them, and it is only the rise of Titanium that has really diminished their use. Then again they are a weird bunch, any cold soakers in the UK?
