We have a fireplace box that is no longer useable. For years  I have just placed a screen in front of it but this year I thought I would shop for some electric inserts. This is really a nice set for the price. The flames are fairly realistic, especially the ones that reflect of the back of the box which have caught me off guard a couple of times! Lol! It also does a good job of taking the chill out of the room with the addition of the heater. My only negative is I would like the "flickering, glowing" fire light to be more realistic.
