Conclusion: I'm not sure that this radar detector works as advertised. I used it on many long distance trips. I have passed several radar traps without any warning whatsoever from the radar detector. In fact except for the occasional false alarm, it has not given me one legit warning in 6 months of use. Even if the police in my area only use instant on radar, this detector should pick up if people in front of me when they are flashed by the police.
Summary: This product is an absolute waste of money, I got a ticket from Lazer on Ohio turnpike, The alarm went off after the COP flagged me to pullover. It does not alert for K band or X band more than 0.10 to 0.20 miles which is not adequate immunity to the radars or lazer traps
