Hi;
If it ever makes it to market I could see it for a backpacker with deep pockets. It is slick in a techie way to be sure!
My money, or lack thereof, would probably stick with the good old repurposed fridge/stove/hibachi grate and some rocks...flat, wrap in old newspaper also used to help start fire.
I do confess I've personally upgraded to a collapsible that is just 15" round by 5" high collapsed that is legal to use on the ground or toss on a picnic table even during a fire ban.
All that said, I'm still a gear whore and I can hear my backpack clamoring for this! *laugh*
