The clip on one of mine snapped off. I called to order more because I wanted to have plenty of spares should it happen again, I wanted to pay for them. The lady on the phone said no, they are a warranty item. I said, but I want a few of them so I will pay for them. She got my address, refused to accept payment information and soon after I got 3 clips and 3 spacers (I dont use the spacers) in the mail. Pretty good service in my book.
