Easy to fit, only have experienced noise in severe winds, which would happen anyway - otherwise dead quiet. Had minor issue with one bar moving slightly under slight weight, but was fine after re-tightening.

Update 3/8/16: EXCELLENT Customer Service. I replied to a company follow-up email asking me about my experience with the product and let them know about the headaches and the next thing I knew I was receiving a refund. You can't ask for better customer service than that. Thank you, 1 Body. I won't hesitate to try other products of yours that may fit my needs. (I do wish I knew which ingredient was the issue :-( ).
