I have used this stove this past winter for winter backpacking. It's very easy to use, flipping the canister when you need to. Yes, there is a bit of increase in the flame when you do flip it; but that's to be expected. I use it with a windscreen and I don't bother with the piezo lighter - use my own lighter. Compared to my whisperlite fuel bottle stove, the spider is much, much easier to use. I have only used it down to temps of 15 degrees, so can't say how it performs when it's colder. It doesn't take up that much extra room in the pack. Kovea makes great stoves. I used the Kovea supalite on my JMT hike.
