Srx!
I know it sounds like a Caddy model, but it is also a laser jammer made by passport, and is on the website that Blaise posted.
My experience is that laser detectors don't work worth a flip if you are on the road by yourself. And around here, San Anotnio, Austin, Dallas/Ft Worth, and New Orleans are all destinations where you get miles and miles of open road. And them smokies are behind every bridge (especially when you cross onto the wrong side of the Sabine River).
Texas state troopers are rapidly moving away from radar into laser. The only thing that works - (almost) all the time is a jammer.
The SRX is a cool little device that is installed "integral" to your vehicle. It has a tiny user interface that mounts over your mirror, and has two detector heads. The front one mounts under the hood, and the back one mounts on your license plate bracket.
It doesn't get the rating of the valentine for only one reason: it costs $1400 and is not portable.
But if you want the BEST, in my opinion, this is it.
