I love the look of rock and really wanted more of it inside and outside my craftsman style house.  I started researching options, and found the stacked stone panels from Genstone.  After I watched the installation video, and added up the cost, labor, and installation requirements, it was a no brainer.....buy the Genstone.  The product looks great, has an awesome warranty, and is super easy to install.  The "concrete rocks" are not real either, and I didn't want the mess and weight in my house.   Everyone who has seen my wall has loved it, and I am very pleased with it.  I am currently working on my second project using Genstone Kenai panels, and I would recommend them to anyone....
