Whatever you get is infinitely less effective than common sense.

Lots of police now use nothing more that stopwatches - any detector no matter how effective is defeated using this method. Plus, many use instant on detectors. They don't leave them on - they fire them up and sense your speed in seconds leaving you no time to slow down.

I think they're all a waste of money, but it's yours to waste...
