I have only had the Duraflame elec. log for a few days and I am really enjoying it.  It slid easily into my fireplace opening, the flame & crackling sound give off a very nice ambiance (crackle is pretty realistic).  I haven't used the heating feature much yet but I think it will easily warm my living room.  I used many of the other reviews with pictures to make my decision.  Glad I purchased, will be nice to look at this winter.
