This was one of the only "modern" looking electric fireplace inserts that we could find (which also fit our fireplace opening). I was skeptical of how good the flames would look, and I was proved wrong. These look very realistic and have a nice randomized effect. We fooled several visitors that thought it was a real gas insert. The heat it puts off is actually pretty decent too, and completes the "cozy" feeling.
To compensate for the extra height, we added a nice piece of black walnut beneath and it looks like it was made to go with it. Also, love the reflective rocks that come with this. They look great when lit, and help refract the light. Much better alternative to fake logs when its not lit.
The insert box is a little tricky to position perfectly, but I just created a support out of stacked 2x4's to support the box from tipping backwards.
All in all, I'm beyond satisfied with the quality of the unit and how the flames look. Such a cheaper and easier alternative to gas.
