I've been running with a valentine radar detector in my carrera for a few years..and I still get tickets..instant on radar

Now with the 911Turbo,i've updated to a PhantomII detector/jammer.Twice over the weekend it went off while i was
doing around 85mph in a 65 zone,no tickets

The manufacturer claims they will cover any ticket i get as long as its for 20mph over the limit or less..
For you people that like to drive fast..
