Has anyone here got any experiences - good/bad/indifferent - with the Spot Personal Tracker or Spot Satellite GPS Messenger that they would like to share? I have searched around for information from people who have actually used them here in Thailand and neighbouring countries, but can't really find much, only some discussions about the concept in general. Personally I wouldn't rely on the 911-feature of these devices in this neck of the woods, but to have someone else be able to see where you are, whether you have been stopped for a long time, and to be able to send off messages saying you're OK (or not, as the case may be) with no cellphone coverage is something I would be interested in.
