That Soto Pocket Torch was my first torch lighter. Such a great idea, I really wanted to love it, but…….
1. It will not work with Bic lighters, only the square-ish Scripto type, which are getting harder to find.
Several brands fit, but really only the Scripto worked reliably, and even then they would often require "hacking" to get a big enough flame to work well and even then the torch flame was still pretty small. The small flame was OK with the Vapor Genie (Glass) but too weak to heat the Lotus unless you're really patient.
2. You're using probably the worst butane you can buy: the stuff they put in $1 disposables! My Lotus plate would get black after a few sessions, presumably from the impurities.
3. You go through lighters fast, and they aren't refillable.
4. It will sputter out with the flame pointed downward long enough.
I still think it could be a worthy addition to a travel kit as a backup, and if the torch fails you've still got a regular lighter inside (good for Vapor Genie)
I hear it works better at low altitudes. (I'm at 5000ft and often vape higher)
FYI: REI sells these in the US, and are good about returns so you could always try and only be out the cost of the lighter if it wasn't satisfactory.
The best I've found is the Zico, also sold as the Arc Turboflame, which I think has been mentioned here already.
, so I finally got this cool ROOR water pipe: The "Inside Standard" model with 14mm joint.
it goes with me wherever. i have noticed though that it is not very stealthy at all because of two handed operation, having to focus vision to the vape, sound from the lighter and generally suspicious look of the whole activity. so i tend to head to the bush or other quiet place to use it. 
You better watch out for space debris up there
