I use this for burning off limbs and brush, and it creates a very hot, fast-burning fire. A huge improvement over burning a pile on the ground, and easier to control should a gust of wind come up. Like others have noted, the bottom panel droops, but I just set it over two extra bricks I had, and they supported the bottom just fine. I suppose a design improvement could add additional tabs on the bottom panel that slot into the side panels, but this isn't a deal-breaker by any means.
