This is a beautiful fireplace, and extremely well-built. cam locks and inserts are all metal, not plastic or wood, and the construction is heavy and thick. This is not cheaply made, and looks great. The only negative is that the back is not finished, and mine is in a corner by an open stair, so the unfinished wood is visible. I have to paint it. Regardless, the fireplace itself is really nice, and I am loving this cabinet.
