First let me say I know this is NOT a gps product. However they company tells you that there are 3000-5000 users near you and when one of them "comes near your device" you get an update.
So it sounds like it should work. However it doesn't. I can log on today 15 days after my devices were put out and get updates saying they are exactly where I left them. But they are not there.
This might be a good thing for your keys but there must be a better product!!
Oh and don't bother with customer service they didn't respond to my repeated requests for 7 days. And when they did they didn't even address my issue.
Product or Service Mentioned: Trackr Bravo Tracking Device.
