I tested it out last night and I can honestly say it's neat and it works. The only problem is the application is a super battery hog.

The application is set to not transmit your location unless it detects that you've moved 15 meters or more. Unfortunately the application drained my battery dead in less than 12 hours sitting on my bed site table.

It could be handy to use once in a while but it's definately not something to leave running all the time.
