Summary: I only had it a week; however, I put the device through numerous test. 1st: I use the computer to set up the device and downloaded the apps for my iPad and iPhone. I program it to send me a email and text message to follow the device, monitor battery levels and power off. I also added my wife and two daughter to track the device. 2nd: I took the device for a test drive and had everyone track it. Performed excellent!!
