Update, I talked to Todd at NSA and reminded him that when I had my failure problem that I was told that my only option was to purchase the new style coupler unit, He now says that I could sent my whole unit back they would have repaired it, that was not offered to me. I told him that he should stand up and fix the old units without trying to make money off of a warranty items he said that he would do so, also I told him that wasn't asking for any money back or anything else. All I wanted was for him to respect the stated Warranty. Hopefully he will comply.
