I’m very happy with my Callaway Grand Electric Fireplace but can only give it 4.5 stars.  The reason for 4.5 and not 5 stars is because the brackets to hold the fireplace insert did not have pre-drilled holes.  The buyer has to drill the holes themselves and risks damaging the front mantle piece.  My suggestion is that the manufacturer should pre-drill holes for the brackets, otherwise, buyer be careful when putting it together.
