I just received my fireplace insert......everything is in working order. Does not heat up an entire room as stated . The heat quality is no different then any other unit on the market. It heats the area around the fireplace insert ....not the room . The fireplace insert could of been a bit more realistic but at this depth I can understand why it isnt. This is not flat and it does not look good used on its own. I had a mantle that was really deep and this should work out so I wont have to adjust it ....it should fit into the  spot easily.  I gave it a 5 because its meets my needs .... but like I said the heat is average and basically  no different then other models .
