I had a handyman do the install on this product. Installed a total of four systems. Had one minor chipping issue but it is not viewable. I watched some of the installation and the amount of time and skill it took. I highly suggest that you are pretty talented with these sort of projects or hire someone who is. There is a possibility for a lot of cosmetic damage if you are not very handy. The overall look is really nice and I am not sure why some of the reviewers did not like it.
