TEN colors could not improve this fake looking  flat fire. I am replacing an existing fireplace insert, and there is no comparison. The heat vent is 1/3 the length of  my old insert and so is the heat force. I bought it for the additional  warmth in the den room, so I am disappointed so far.  Designer should look around at other inserts to learn how it could be done .  Not looking for a light show but a fireplace . Some are actually weird and scary.
