I keep telling him that but he's stubborn!

Actually that's BS! The military and NASA both REQUIRE them. They're a
lot more resistant to vibration for one thing. Besides I didn't say
MANUFACTURERS, I said "individuals". MOST manufacturers are only concerned
with how cheap they can make the stuff, they don't give a hoot about
durability, reliability, repairability or anything else.

I seriously doubt that.
