No Martin... it's the fact that mine are used sometimes 3, 4, or 5 nights a week...   It's simple work-hardening of the spring, and one day, snap... done... Like repeated bending of a coat-hanger.. eventually the wire loses its 'flex' and just snaps....   Even using them 3 to 5 nights a week, the DO last years... but eventually they do die...

I resent the 'abuse' implication on your part for that matter...
