I got this to replace a well worn grill for wild camping over an open fire.
I gave it a go before I left and was impressed with the build quality. Everything was really smooth and well machined, the construction, although fiddly, was easy enough and took only a couple of minutes, even when not following instructions.
In the field this performs significantly worse. Firstly the construction involves a large number of small components (each individual run, and the screw cap) so you must make sure not to get them lost in the leaf litter. On a fire it performed well, although the stick like legs easily dug into the sandy base around the fire, necessitating some DIY wood supports. After resting a pot on the top, the rungs easily bent. The pot was a Zebra billy (like most wild campers use) and had about 1.2 litres of water in it. I would guess it weighed about 1.7 kg.
After use, it then came to deconstruction. Given that I was burning pine, the rods were now covered in pine pitch and were very sticky. The pot had also bent them slightly, although not significantly.
The pitch made the screw-thread incredibly difficult to use, and the bent rods didn't really fit back in correctly without a bit of "coercion" from a nearby rock. The end result was obviously dirty fingers from what was on the grill.
Compared to my old grill it is certainly smaller, weighs about the same (it's incredibly dense in the compact form - obviously), more fiddly and leads to filthy hands. You cannot do the old trick of "I'll put this into a bag and deal with it when I'm closer to civilisation" which was always preferable.
Conclusion: For a geeky gimmick where you can wash your hands and only intend to cook food on it, rather than use it to place a pot on, ideally on a hard surface, it's good enough and starts life very well built. If you're looking to use it in anger, in more rugged situations, don't bother as it is pretty flimsy..
