Exceptional!!!  I was so pleased with how easy it was to put together. The quality is great, well constructed and the finish is beautiful.  I love the decorative pieces around the opening.  The mantle was a little rough but nothing a coat of poly won't fix.  One hole on the back top panel was off so I was not able to use the screw provided.  I used one of my screws to secure it. I have not plugged it in yet so I can't comment on the flame or heat.
