I am very pleased with everything about this attractive, functional wall art.  The flame is mesmerizing, and the heat output is very good.  I like that the remote works intuitively: I didn't have to read the manual on how to use it.  On/off works the flame.  The 2 buttons below are on and off toggles for the two levels of heat.  The bottom button is a dimmer for adjusting how high the flames are.  I only used enough stones to go across the bottom of the display, as the stones add a lot of weight.  I also drilled an extra hole in the wall brace so I could secure the brace into 2 studs for added strength.  I only wish it had a thermostat, but for the price, it's such a good deal.
