Been to kenmar camping on my way home today and got one of these nice little bit of kit boiled some water and a tin of beans heated up quick and did not burn hands and ideal for meausreing cups of tea etc
Even simpler.
Tin mug with string wrapped round the handle, wet the string and stand it on the burner, take it off when hot enough. Drink coffee instead of tea as it doesn't have to be boiling.
After you've drunk the coffee, heat the beans 'n' sausages.
To me one of the considerations is whether the space inside is wasted, stuff that telescopes together is preferable.
I know you always stuff them with dry socks etc.
It's not falling off, it's an upgrade opportunity.
