Hummh.  I have about 8 or so D7's between my oriingal prototype and all
the ones at work, and so the age is from 15 years old to about 10 years
old, and not one of them has failed for anything, though  several have no
control knob from having bounced on concrete numerous times.

Yes, but 100,000 cycles is sure a long long time.  Let say 20 entries per
marathon 5 marathons a year, that is about 1000 years life.  I doubt even
Kenwood will be around then...
