Bests & Worsts Reviews from Amazon

First, let me identify my goals for this Tracking Key. We run a service business. We have a need to recapture the routes the vehicles have traveled for the day, what stops were made(addresses), how long those stops lasted, and the exact time of the arrivals and departures. Also, we wanted to view the route on a map to identify instances of getting lost, and have a printed report of the stops and times for the day. On the first day we clipped this unit under the seat of the car. When we downloaded the data for that day, it only showed 3 of the 6 stops made, and there was no accounting at all for about 3 hours of time. Thinking it might be a placement issue, the next day we placed it on top of the dash, in plain sight, where the instructions said it would get it's optimum satellite signal. It still took almost 10 minutes to acquire a GPS signal to begin tracking once movement began. The unit is not sensitive enough to awaken within the first few feet of movement, and takes much too much time to acquire a GPS signal, making it impossible to recapture continuous data. Other design issues are lack of an on/off switch so the unit is always on, draining the batteries. The manufacturer says the unit goes to low power mode when not moving but see my comment about that feature. Also, to change the batteries, you must remove 4 super small screws. This will lead to stripped screws in short order. There needs to be a latch device instead. We are sending it back for a refund.
