Hi !
I bought what looks like a very similar one, more than ten years ago, here in France, under another brand name. The can was dark green and the jelly pink.
Very light, do not take much place, easy to use (just be careful when you want to shut it off, by closing/putting the lid back on ... it's hot !!!).
As a refill, I also bought a tube of firelighting paste (brand name = fire king, by Sipuro, a swiss based Cie).
The "stove" was sold along with a aluminium quart (about 25cl), inside which it was stored.
It was enough was my purpose : to heat some water for an instant soup, or a cup of tea or coffee. Enough for a warm break during one-day hikes in winter.
Only problem : I can't find the paste anymore .... so I use this "stove" with esbit (or look-alike) solid combustible. One piece is OK to boil 25cl of water in a few minutes.
Regards.
Alain
