If you are looking to purchase something like this you probably already know the truth in your gut. I certainly did. But in a state where you really want something to work, excuses can be paper thin and you still buy them. So I needed clear evidence, and I certainly got it. This little device did exactly what it claimed. I was able to track my vehicle 24 / 7. I used the cheapest plan: $24 a month for 60 second interval readings. With this plan the tracker's battery lasted 14 days, more than enough time to confirm my suspicions. Once it was over I was able to cancel the service without any problems.
