I HAD NEVER SEEN THIS PRODUCT BEFORE, BUT TOOK A CHANCE ON THE PURCHASE BASED ON THE REVIEWS. AM I EVER GLAD I DID!  IT IS SO VERY EASY TO USE. THE "HOW TO" VIDEOS ARE VERY HELPFUL.  I USED THE DESERT SUNRISE STONE TO BUILD A WALL IN MY RECORDING STUDIO, WITH LIGHTS TO BRING OUT THE COLOR AND HIGHLIGHT THE STONE.  I HAVE ALREADY TOLD SEVERAL FRIENDS ABOUT GENSTONE!
