The listing claims to heat a 400 sqft area, but it doesn’t. The heat is indirect, forcing the warm air down to circulate around the room. There  isn’t a warm feeling at any place in the room. It’s easy to put together, but the fit isn’t the greatest. Some of the connections are not right. We bought two identical pieces, and one had a much better fit among the pieces than the other. Overall, it looks great and is a nice accent piece. Not reliable to heat a whole room on its own.
