I have never personally worked with steel before, as I don't know how to weld, and wanted to do a DYI project in my own garden. A landscape designer friend of mine had recommended this product and so I thought I would give it a try. As I was figuring out how much to order, I found the owner extremely responsive and helpful. The materials arrived in a timely manner in a flat cardboard box. Everything fit together exactly as promised and as shown in the videos. It is very sturdy retaining wall and we are now ready to start planting the garden.
