Any update on users of these devices? I’ve just ordered two units after a demo from one of their reps. Tells me the reserve battery is one hour approx after it is disconnected from the battery, but I will email you when the disconnection happens. So you can track it and locate the car hopefully in that time if it’s still moving. No SIM card, just $12.95/month after the included 12 months. Pay for 11 up front and get the 12th month free.
