Great built-in electric fireplace.  I was concerned about having a built-in with combustible materials surrounding it on the face of the wall but it is perfect.   The blower blows the heat down and away from the unit so it is placed perfectly.  The LED is a touch sketchy for realistic flame but for the price we got more than we expected.   Installation was simple and the specs were spot on with the measurements.  The only thing this lacks on the installation is information on the two different style of rocks that come with it.  I tried searching the web for information on it and couldn't find anything.  I searched all over the unit to try and figure out how to take the glass out.  Come to find out there is 2 small hand turn knobs above the glass tucked in each corner that you turn out then gently take out the glass.   All in all its going to be a GREAT piece to our house.
