I just bought the kit because the ground where we live has so much clay, it is hard to dig for a garden and also does not drain well.  I bought this kit and had it set up within minutes. The only issue I had was attaching larger clips for a double height bed. A couple of the clips broke (need a hammer to connect but not difficult), but the company was prompt in sending more clips. 

Anyway, size us perfect, can move around easily, uses recycled plastic, a very well engineered product.  I haven’t yet planted but am on the way to do this.  Also, the planting guide and info about soil to use was great.  I highly recommend this product and company.
