Fireplace produces a high pitched screeching sound that makes hard to be anywhere near the fireplace when it's on. This is without turning the heat on. Understand that the heat feature makes noise and that's actually less bothersome than just having the flames on.  The LED lights could have been better matches to the flames for a better overall aesthetic. 
The metal foot in the middle of the unit scratched up my floor was I was moving it back to the wall after running cables through the cable holes. So if you have wood floor put a slider under it during assembly.
Finally the doors on the front do not fit all that well. it requires lots and lots of adjustment to get them sorted. Never trying assembling any furniture that required that much adjustment.
