Thank you Morgan. Some reviewers on Amazon have had negative remarks
about the cell phone pairing process as well as some negative remarks
about the ability to reliably receive inbound text messages. Any
observations in those areas?

Maybe one way to keep the subscription cost down might be to buy the
low end $10/mo subscription and not use the tracking every 10
minutes. Instead sending occasional track reports by pushbutton say
after leaving a thermal or when low. Is it possible to send
individual track reports or do they have to be at the programmed
intervals?

The other way to keep the subscription cost down would be to change
from the $25/mo to the $10/mo mode in the off-season. Of course, here
in AZ there isn't much off-season.
