I'm not sure where the Watchdog report would be, it might not even be Watchdog but I remember seeing something on TV.
It's nice that the cable is easy to change, Kirby have always made it easy for the end user to change I think (apart from that torx screw on the cable cover which most people won't have at home) but I also wished I could just wire another cable in, rather than have to buy the right one.
