I've had a Coleman xtreme (single burner) for about 4 years now and it is a good stove. I've used it in pretty cold temps, below 30F for sure. The only issue I have with mine is that the fuel control valve is difficult to adjust down to a low simmer. Not impossible, just a bit of a pain.

I think it's still lighter to carry a "Pop can" stove and alcohol though when the temps are above 40F. But the Pop can stove is hard to light when it's cold. I wasted a lot of fuel on my last trip dealing with that problem. I've been thinking of possible solutions since.

First I'm going to try and fashion a sort of saucer to set it on. The saucer should hold a enough fuel to get the stove hot enough to light off in cold weather.

I thought I might also try making something that will hold a votive candle under the stove to help heat the fuel in cold weather.

It seems that there should be a simple, easy, and lightweight method to improve cold temp performance for these.
