Query: nice appearence, doesn't really work

They have been around for some time. My first one seemed fine until DST when I found out it did not adjust "atomically" as advertised, but just used the calendar. I could have set that manually if it had allowed me to choose a time zone east of Boston. After extensive email activity, LaCrosse sent me another one. It truly noticed something changed on the correct DST date - it turned wildly for more than 24 hours. Eventually I pulled the battery to stop that. After letting any residual charge leak out for a week, I hoped it would reset, but it never did. I've given up on it.
