I am in LOVE with this fireplace.  It helps that I put it in a room that has similar crown molding, so the fireplace really looks like it is part of the architecture.  It's so beautiful.  The instructions don't give any guidance for how to fit the clear rocks into the display.  Although I have seen other fireplaces with the stones, there didn't see to a place for these and it was really hard to even try to place them; but, honestly, it looks great without them.  Maybe eventually I'll play around with it again. Also, there aren't any holes drilled for the hardware that secures the heater and keeps it from getting pushed back.  It's not a big deal, we just had to grab a drill, but important to note... I would 100% recommend this despite the two tiny issues I encountered.  I wish I could put one of these in every room of my house.
