Unlike Mr. Parish, e-mails to customer service and telephone calls where they promised to call back in a couple hours have yielded exactly nothing. I have two T80s and simply want a firmware upgrade from my present 4.03 to something after 5.0. The two T80s are not in service at this date, so I can
t comment on their reliability, but if anything is wrong, getting them fixed may be a big problem.
