I had ordered the medium  Clairmont Fireplace Screen and Bi-Fold Track-Free Smoked Glass Door by Pleasant Hearth and received it on time and in great condition. Read the directions and followed them. My fireplace opening was a perfect fit with the riser. My estimated time for installation was about 30 minutes, not including the reading. It should be 5 stars, but I agree with other comments that it should have more insulation. Understanding that it is just for the heat on the surround, but you do need more for the brick and air gaps.

Pros: Keeps the room warmer with the insulation provided. Easy one person installation. Nice addition to my livingroom. 
Cons: Could use more instulation.
