Easy to install.  Good Design (we like the modern glass rock option). Our basement family room heated up nicely and we were able to enjoy movies without the need for cozy blankets for the first time since buying our 1940's home. 
*You do need to mount the fireplace high on the wall if you have small children in your home as it sticks out far enough for someone to hit their head on the corner of the glass frame.  The instructions say that the glass can get hot to the touch.  We have not experienced that issue.
