Incredibly small, even though I looked at the specs I was still a little disappointed at how minimal this thing is. Also, the heat is a little strange, seems like it shuts off consistently even though the room temp. hasn't matched the set temp. of the fireplace. Also, the top "mantle" was bowed upon arrival. I'll eventually try to set something heavy on top for a while while it's not in use to see if it does anything, but don't want to mess with it too much as it's cheap mdf/particle board.
