I upgraded my old LightSpeed to a 20 3G sometime last year. Since then the
battery box has had to be replaced. Cables tended to break where they
entered the old type of battery box. The new battery box has a better
design.

The biggest problem I have had with headsets is not really the headsets, but
some of the new Cessnas that put the jacks up on the door handle so that the
cords come straight up out of the jack. Everyone complains about snagging
and breaking cords with these.
