Multiple dial combination locks often come preset to some default combination, usually 000, and people don't have to be told to change that, so the concept really isn't above an average user's intelligence. People need to stop refusing to not be idiots when it comes to the digital stuff. And I don't mind letting those who can't be arsed learn the hard way.
Sadly, as in this case, it's often others who fare the worst, so I suppose something needs to be done, but, like I said, I wouldn't shame the manufacturers in this instance: if any Tom, Dick and Harry know that 000 isn't a good combination to guard their bikes, why do they think that admin/admin is good enough for their security camera?!
