Say all you want about them, but I think it's pretty telling when the engineer that designed them stated they needed to be changed to prevent accidental discharges in both internal memos, as well as in interviews over the issue. From his statements and the fact that they didn't change them out until just a few years ago cost them many millions of dollars. It's a shame when the issue could have been resolved with very little money outlay if they had listened to him decades ago when they were first invented.
