Not dependable at all times.
Installed two trackers on two separate vehicles. Both trackers are working, but twice on separate occasions, the two trackers have simply stopped transmitting accurately for over 8 hours. The transmitters show the vehicles stationary at their last stop when in reality, they are literally parked in front of me. One tracker started again tracking accurately on its own. I’m currently waiting to see if the second tracker will start up again. I would not put my full trust in these trackers to give you timely information as they appear to go offline unexpectedly and provide false information when they do.
