I have also been using this pretty exclusively now for the last couple of months as opposed to meths.
Last weekends trip was an Exmoor excursion training groups for Ten Tors where the temperatures didn't get much above freezing and even dropped below when it was time to cook my evening meal. Like you say Simon, it doesn't like being cold but I just don't like using gas stoves and even some of those being used by the young folks were struggling.
I will be staying with it for some time to come I think and have plenty of trips in the diary what with Ten Tors and DofE. The daughter can have my Trangia gas stove and I will have her meths stove as an exchange so I have a back up if ever needed.
