Waste of money. I typically drive 10mph over and can't tell you the last time was I was pulled over for speeding, in probably 8 different states. Police are usually looking for 15 and over. I save my fast driving for the road coarse.
I did look into the jamming systems recently and all the research I found showed they were useless and in some cased increased the useable distance of the police radar.
