That's a pretty awesome setup. I like the combination of bottle, stove and drinking cup. It seems very versatile. And all for roughly $6.00 US.

The stopper would make me a little nervous though for fear of food matter getting caught in the cork and over time brewing up something nasty. I'd have gone with a screw top with o-ring seal and pop-up pressure release valve though. Of course that would easily double or triple the price. Maybe it could be replaced by a rubber stopper. I'd also put an eyelet in the stopper and attach it to something removable so I wouldn't loose the cap. I'm good at loosing such things. <img src="/images/graemlins/smile.gif" alt="" />

I can't say I've seen better though.

I understand what you mean about carrying it. Perhaps you could attach a simple carabiner or maybe even a velcro cable tie to the stove and then carry it horizontally attached to your belt across the lower part of your back to keep it tight to your body. However, sitting down might be a problem at that point.
