Summary: I've had this item for almost a year now install on my vehicle since January 5, 2011. It works fine for the most part and provides somewhat accurate reading of the area where the vehicle is located. Not precise, but gives you a good idea where in the area the vehicle could be find.
Summary: Don't do it! I've invested in over 6 of these Entourage CIS units, and 3 have failed. Customer Support is NON EXISTENT, with the snottiest French-Canadian elitist attitude you can imagine. I logged on last year and my '65 GT350 Shelby had been off-line for 2 months..
Summary: I have 3 other types of GPS trackers. All have their benefits. This one sends an update every 10 minutes. You can request an update and it may take as long as 2 minutes. It continues to send signals even when the car is off and does NOT use enough energy to run the batter down.
Summary: I have one in my wife's car and now ordering one for mine becuase of our cars are considered "High Theft" category. When I have 2 cars costing more than $70,000.00 each, then this is a mere cost for this insurance.
