Very well designed, with flexible configurations. We'll see how they hold up to the elements.One "opportunity for improvement" is that the caps for the corner posts have holes in the center, and there are no caps for the feet, which may be placed on/in the earth. It would have been really nice to have the option for closed caps and caps for the feet. Where I live, we have LOTs of spiders, lizards, bees, and even very small snakes which may nest in the corner posts. Also the feet will no doubt pick up some dirt if/when placed on the ground, meaning that if they are moved to a clean area (which is likely in my case), they will likely make a bit of a mess. None the less, they are very good for my need (to provide some protection for some plants in baskets and small pots), and I'm happy I bought them.
