Query: Beware Old Merchandise

This is the very same life preserver Amazon sent me except I didn't buy the sailing harness. This life preserver is supposed to have a five year life on the arming mechanisim but the one sent to me had only four years left. I suppose it had been setting on the shelf for a while. They are non-returnable so you take your chances when you order one. I bought a total of three and the other two were okay.
