This product is OK at best. The grade of the steel is quite poor (flimsy). It is NOT like the corrugated window wells that it tried to look like and has very little structural integrity. I would consider lining the interior with 5/4 cedar to maintain the integrity of the walls (which begs the question of why you need these thin metal walls, really). You need to assemble them with screws and that alone will suggest to a gardener that there are much sturdier products on the market.
