I am very impressed thus far with the quality and the accurate instructions. This is not a beginner's project by any means. Take the time to organize before you begin. I have a bit of a slope to the backyard that had to be accommodated as well. There were a few missing parts; which is not unheard of when something literally has 1000s of pieces, but the company was quick to respond and got them to me in a couple of days. I would not hesitate to recommend this product.
