@QuittingVegas this post is for you, sorry for being such late at replying to you!
Here is my look at the stratosphere lighter, from Xikar (there is a stratosphere II replacing the model I have, with an improved lid and some fancy useless rubber design)
You can found it on Amazon or somewhere else for 20$.
This lighter is a single torch, completely windproof that works at high altitude and wich come in a rubber shock proof case, with a water resistant lid, a fuel window and the flame is adjustable with an easy wheel of the bottom. There's also a rope to fix it when you're climbing a rock ah ah.
The flame is wide at his base, covering 1/3 of the cap's heating zone, resulting in less movement while heating (the back and forth movement) and I found it easier than my other single tight flame. If you set the Ti bowl to the first or second position you don't even have to move while spinning the vapcap!
The altitude feature advertised is true, I had it tested at high altitude (3200 meters) with wind and by - 15°c and I can say that it works perfectly at all times, even if it takes one minutes to heat the vapcap in that conditions, you achieve it and you can say fuck to the weather!
At this height, almost all lighters will fails, and this lighter's lid is also water resistant, awesome on the slopes!
The windproof feature is achieved with a little coil in the flame path, the coil is getting red hot but the flame stays blue, and for now there is no degradation or residue produced by this coil on my cap.
This little glowing coil also produce a little bit of light (about half of a match), wich is enough to aim correctly and heat the vapcap in a total darkness. Personally, I found this awesome!
This lighter was offered to me, in order to follow me during a hike, or on the winter on the slopes. And he's serving his purpose very well as stated before in the vapcap thread!!
All I can say is that I love this lighter and I will buy another one if this one's dead, because heating a vapcap on the roof of the world as no price)
Funny things, when you ignite this lighter, the flame produce a softer sound than a traditional torch lighter, wich sound to me like a rocket engine but quiet. Really surprising sound!
