I have not sent my EOS-1D X to Canon yet for the Product Advisory check/repair. When I called Canon CPS, the Tech on the phone told me to wait to send it in, until I actually experienced problems? He made it sound like not all of the affected bodies will ever experience problems? I am curious how many others are waiting to see if they actuall experience problems with their cameras before sending them to Canon. Also, are there any more horror stories of shipping problems (poor packaging), repair problems (parts form someone else's body), or any other problems associated with the check/repair out there?
