Bad design and poor execution.
First the original description had the wrong demensions for depth which is why I bought it in the first place. This has since been corrected.
Second the posts slide over the edges of the steel but the slightest pressure on the steel and they pop out of the post. I lost a lot of soil because of this poor design.
Third they provide a top cap for a finished look and just assume that the unit will be put against the ground solid. If they provided a second set of caps for the bottom then problem two of the steel panels would not happen.
I gave it two stars instead of one because it is steel and the finish on the steel isn't too bad. Could be better but it's not bad. If it wasn't for the finish I would give zero or one stars.
Again good idea but poor execution.
