Has any one heard of this laser/radar jammer for 299$ called phantom because your sppost to be invisible.

 

During one of one the radar detector test that Car & Driver or Road & Track did several years ago, they tested that Rocky Mountain Radar Jammer thing you are talking about...

IT HAD ABSOLUTELY NO EFFECT on any of the speed measuring devices used (radar, lidar). They were laughing at it in the article.

Don't spend $5 for it... much less $300.

 

the only ones that really work are the
phantom rcd
phantom rdc xp
and the scorpian xp

test done by jamradar.com

all else failed

 

I did some research of radar detectors and decided the Valentine was way too expensive. Bought the Bel 870 for $225 shipped to me. So far, I love having a radar. I drive alot for works and am amazed at how many times I have been alerted to a radar (usually turns out to be one of those stupid neighborhood speed alerts).
