Has anyone tried this device in the BWCA or Quetico?  I used it on a solo trip last fall with mixed results.  Apparently, there was a satellite outage, so my spouse became concerned when the email messages suddenly stopped mid-trip.

I have never used any other communication devices on previous trips (nor will I be likely to in the future), but the SPOT appealed to me because it let my family know I was OK while out there by myself.
