Hi
I bought one and am absolutely chuffed to bits with it, I don't just use it for paragliding / motoring but I do a lot of fell walking and mountaineering and use it there as well, it's small, lightweight, extremely easy to use and very user friendly, great for tracking where you've been using the track log system in conjunction with Google Earth and it really does work, I've not used the 911 function yet, hopefully will never have to but have used the help function once and everyone on my contact list was contacted, there is a yearly subscription but it doesn't cost the earth and it gives both me and my wife peace of mind, you can even send a test call everytime you switch it on to make sure it's working correctly.
