Interesting. The label does say 'butane propane mixture'.
With the aerosol-style canisters you have to find out whether they have a fixed internal tube, a loose internal tube, or no internal tube. Each sort needs handling differently in the winter. They can work if used properly.
But a word of caution - well, 'some' words actually.
It is highly likely that these come from China. My experiences with Chinese canisters has shown two problems so far:
* the screw thread on some has been so badly formed that a stove would not stay connected. This is not really a safety hazard as the valve would simply stay closed under these conditions (I think).
* the fuel may be full of dust, and the dust can block the jets and valve very quickly when used inverted.
In addition, I am not sure whether the valve is a Chinese copy of the Lindal valve. If so, the items may be in breach of copyright. Even if the copyright has expired, I wonder whether the quality control on the Chinese production matches that of the German Lindal group. I emphasise that I do not know, but I would be concerned.
