When I ordered my F35, there was an "Additions" button to select this set. Clicking it added the set to my cart, so I expected everything to ship together. When the F35 arrived without the pulleys and weight stacks, I contacted customer service and was told they wouldn’t ship until the week after February 28. It would have been nice to know this before spending an extra $1,000 on the upgrade. Now I have to order additional plates just to use my equipment. Overall, I’m disappointed with the lack of communication.
