I use it with Snowpeak Mini Solo (big and small pot)
Caldera Cone (proper original one)
So far I've pretty impressed with it
It's very neat and compact and takes up less room inside the pot when stowed away, the simmer ring is sort of useful but not a show stopper (although I did use it to simmer the peppercorn sauce on the Winter Bivi)
Things I've noticed.
It's more efficient than my previous burner (Trail designs 12-10)
It's also a lot stronger and less prone to damage
It seems to boil slightly slower but only marginally
It kind of 'throttles' until it settles, I think I maybe put more meths in than when Stu was designing it. I usually boil 800ml in one go.
It's much easier to recover unused meths from than my previous stove.
As somebody who went through about 10 different Meths stoves before settling on the Trail Designs 12-10 stove (which is very very good), I am now settled on this (Cyberstove?) as the new go to stove.
