It's the only legal way to heat food in Rocky Mountain National Park while backpacking. Also the only legal fire in National Forest during fire bans.
Both are where I've done most of my backpacking.
A stove is the least-impactful of heating methods in heavily used areas.

In my test case I was checking for stored fuel usability in the event of home power outage. I also have a 2 burner propane stove for car camping and diversity of equipment and fuel supply.

I was disappointed that the pump failed but really surprised at how difficult field repair would be. The pump cup ought to be retained by a reusable clip rather than a one-way push on washer that has to be mangled free with needle nosed pliers.
