Changing this every year is nonsense in my opinion. Guessing at what date in a year it might go bad seems futile. Just fix it. The opportunity for failure is the square of the parts, two plugs, one wire, nine ways, that... by itself, has opportunity for failure. Reducing this to a wire is one way for failure. In my case it was/is not the failure of the wire to the metal connector, it's the connector to the connector pin of the socket. This is not a crimp issue. The soldering may be annealing the metal portion, spring action, of the female side though so it's more flexible. I thought the hot glue was a good fix too. Interesting that both the tx and adapter have options for wired connection.
