I originally ordered to place in a car that I let a family member borrow. They were not honest about places they were going. I got tired of being lied to so I took the car back. I used in another car to travel from Tennessee to Florida with my daughter and granddaughters. It made this Grandma feel a little safer knowing my hubby was aware of our locations at all times. He even knew when we were speeding on the interstate. I like that there is no contract to use the GPS tracker. You can cancel and sign back up anytime. Soon it will go into a car that my 16 year old granddaughter will be driving.
