I was looking for an artificial stone to put in my house behind my suit of armor.  After checking out several brands I decided to use GenStone.  Very pleased with the results.  The panels are easy to work with and the look is fantastic.  This was about a one day project.  I used the trim piece along the top of the wall.  The existing crown molding I painted a flat gray and butted the trim against the bottom part. Looks great.
