I have nothing but great things to say about your spiral staircase and the ease of installation. Directions are well written and all diagrams made sense for assembly. Installation took me two days by myself. The product was delivered when promised and the quality was what I expected it to be. When I did need a question answered, my customer service person was very willing to help me to make sure I would be completely satisfied with the finished product. Thanks again for an enjoyable two days.
