O.K. found my answer. Could still be good but they are so cheap...
Most are dated. Law enforcement will ticket you if by chance they check you, it's expired, and you don't have another on board to cover your behind. Yeah, they're not expensive and easy to replace. I always fire my old one to make sure it works as designed before I replace the old one and there's always at least one more regular vest on board.
Just ensure you buy the correct rearming kit. I have to go back because I bought the wrong one for my auto inflater! Doh!
Thank you! Good to know!
