Love this Stove
The jetboil system is simple and effective. We've used it on trips to warm and cold locations with little problem. I like how the whole thing compacts into the pot and you can also fit your jetboil utensils in there as well.
Recently, the igniter has turned to hit or miss so we usually bring some matches or lighter to get it going.
It's highly suggested that you bring this into your tent if it is super cold out and just ensure the vents are open in the tent. The heating element on the bottom of the pot will turn into a cooling element if it's windy and boiling water out of a tent will turn into a watched pot that takes forever to boil.
