I bought one of these stoves during lockdown so only recently got to try it. My first use, due to its weight, was car camping at the end of June.
I connected up a full gas cannister and lit the gas but it flares / splutters (too much air?) significantly and when I turned it down to control the flame, it went out. Cue disconnection and turning back to my Alpkit stove.
Just tried it again in my garden. Same experience. Not at all as reassuring steady and quiet as my basic Alpkit stove.
Anyone on here with experience of this Optimus stove? I could post some badly shot footage to my Instagram account...
