progressive snap shot discount

so i just got progressive and they sent me that snap shot discount thing that u plug into your car. does any one know what this thing really does other then what they tell me . also is their any tricks i can do like unplug-in every so often so looks like i drive less. bottom line is what can i do with this thing other then driving within the law that will help me lower my rate :gotme:

I remember reading up on it and from what I remember it just takes “snap shots” of your driving. I don’t think anyone’s figured out a hack / cheat yet… but I bet one is coming.
