I love these systems. I bought 2 and am glad that I did. They are not easy to install though - they require 2 people and the ability to find studs in walls and perfectly line up sides before installing.  The final product, however, is fabulous. I hired a company who installed both for just under 200.00. It took them more than 5 hours though - so a very good deal for me.  Love the final product!
