Quality control isn't the best. Some ends of the pieces are not squared with the piece, making it look like a bit of a trapezoid. Also the binding around the edges is a somewhat uneven, especially where it starts and ends.

As for packaging, they ship carton folded in half in the carton, which means they do not lay flat on the stairs. There is no reason they could not be packaged flat to avoid this problem.

Otherwise works as intended.
