We've had this fireplace for about two weeks and we've had it on just about constantly.  It's absolutely perfect to give a great atmosphere to the living room even when we don't need a little extra heat.  The flames look great and we love that it can be totally silent.  The only thing I'd suggest is that the cord be centered in the back rather than on the top right side.  My electric outlet is next to the left side of the fireplace and the cord was just barely long enough to reach.
