The unit itself is attractive, and as long as you place it far enough away from the back of the fireplace you are installing it in, the flames are high and viewable. If the unit doesn't have much space then the flames are barely visible. Negative, cannot seem to get the heat to go off right away. I have to shut down the entire unit and wait for the fan to go off before turning it back on in light and sound mode only. Another negative is the sound quality, not stereo sound . Unless it is on a low volume setting, the sound is actually quite bad. Couldn't upload a video to show it working.
