I want to write you to say thank you for the help that John gave me regarding a Stairmaster Freerunner 5600 part that I am trying to track down. While he didn't have the correct part in stock, he was very helpful in educating me about the history of this machine and working with me to identify the right part number for our broken machine.
Great job! It made ordering online from you simple and precise - and amazingly fast! The magnifying glass function on your diagram worked perfectly, and my experience was superb.
