It's a lot of work to put it together,....millions of screws, nuts and washers. My husband and I worked on it for hours. Sharp edges too, be careful. 
I do wish that the sides were a little bit stiffer. I like to lean on the edges a little while I garden. They are very flexible, not good to lean on. I just planted my seeds today, so we'll see how they do. It takes a TON of dirt and mulch and compost to fill it up,....we used large logs on the very bottom to make it easier to fill. Plenty of room for the roots though. That's good. So, now we'll water and wait and see how it does.
