Installed this on an existing paver patio. What I like best about this product is how well everything fits. The holes line up, the screws and fasteners are all the correct length for the pieces. There are a lot of pieces, but the instructions are pretty good. I also want to mention the excellent customer service I received from Yardistry themselves. I had two pieces get blown off the top of my pavilion during construction (my error, no fault in the product) and Yardistry sent out the replacement parts immediately. I had them and was able to continue my project that next weekend. Thank you.
