Wish I'd read the reviews before I signed up as my experience is exactly the same as many others!
With the free trial I was able to accurately track my sons phone as my husband took it for a ride in the car. Once we handed the phone back to our son & paid for a months subscription, my son had managed to disabled all GPS & location services by doing a simple reboot of his android phone. The technical help (English was not his first language) was pretty much useless as I need a degree in computer technology to understand their explanations as to why it wouldn't work - basically all the app need to be rooted' otherwise they can be uninstalled.
So unless everything is rooted, don't waste your money.
