It is a bit heavy, so not much use for backpacking, but if you're camping in an area where you can't light a ground-fire then the firebowl is a handy thing to have. I was using mine at Middlewood, because the ground was so wet and ground-fires weren't allowed anyway. The grill is a bit fiddly but is strong enough to support and boil a full 1.5L kettle. Had mine for a bout six-months too, and use it most times I'm out and camping not far from transport makes it easier to follow the Leave No Trace philosophy.
You could probably make your own similar setup, improvising with one of those fan-out metal food steamers and a cake rack as littlebiglane suggested, but I'm a confirmed gear addict and liked the clever design.
Edit: TBH I would look toward the hobo stoves as a better solution, Woodland Edge sell one that's a good design but it a lot more expensive, and at Middlewood I saw a lot of different ideas for hobo stoves and fireboxes, most of which looked pretty easy to make yourself.
