Yes, the stove was used on High for the tests.
I COOK dinner sometimes, and this requires a low flame to avoid either burning dinner or boiling the lot over. This canNOT be done on the Reactor. The basic Reactor design cannot simmer safely - I tried.
> could the flame adjuster be turned on half way to save fuel but still get the low boil times?
No. What you are asking for is high heating power at low fuel flow: life and stoves don't work that way. Sad.

That depends very much on the weather, at least for me. If it is pouring rain I am NOT going to sit outside to cook. Anyone who does so at 33 F in a 40 mph wind and pouring rain is, to put it bluntly, a complete idiot. They are also risking their life. I cook in the vestibule of my tent, and have done so for the last ... I dunno, maybe 20 years. And I am prepared to put my professional reputation on line (Research scientist, PhD) and say this is safe - despite the lawyers at MSR etc. They are just trying to avoid any liability suits.
> except if the weather necessitates being inside a tent, which mean you don't use a stove and wait out the storm
I am sorry to be so blunt, but this is complete rubbish. You have obviously never been in a 24 hour storm in the mountains. You have obviously never been soaking wet in a hail storm and struggled to get your tent up and yourself inside, shivering frantically. Or, worse still, in a day-long snow storm at 2,000 m (6,600'). Under these conditions you do not fool around: you and your partners NEED shelter and hot liquids, and you need them NOW.

Sorry, but this is false. The marketing spin about this was obviously written by someone with no knowledge of physics. If anything, slightly more canister pressure might be required to make the pressure regulator work properly, but the point is rather moot.

I don't need to wait for winter. I can stick the canister in the fridge. But this is unnecessary in practice. The way canisters behave at various temperatures is very well-understood physics. And I have spent plenty of winters in the snow cooking in my tent.
Yes, you could use the Reactor in winter at 0 C (32 F) with an iso-butane canister and get away with it sometimes. But you would need to keep the canister 'warm' (above -5 C), because at full throttle the canister is going to freeze down fairly fast - especially with a 3/4 empty canister. You could also try doing it with a butane/propane canister, but after a little while the stove will die due to differential evaporation rates. Read our articles on Winter Stoves for more information on this. In practice this can be a real hassle, and we do use remote canister stoves instead.
Time will tell about the Reactor. It looks glamorous, but it has real practical deficiencies imho.
