I've noticed that the newer replacement ones seem to be a bit less flaky
than the older ones. Since roughly 2205-2006. Original stunk, as
accurate as a Ouija Board. Replacement reasonable until it got hot, and
for good measure started leaking. Third time seems the charm. They
are trivially easy to replace thank goodness.
