I've got a hard wired Valentine 1 and a Laser Interceptor BMW specific jammer installed as well.
My wife has escort products in her car, and I find them to false too often, especially with Audi/etc radar cruise control systems. I don't have that issue on the valentine 1.
Installation of both was done by me - its a simple install - the "hardest" part is running the wires to the jammer heads, which is not hard at all.

I respectfully disagree with the opinions on other jammers mentioned above - I'm
pret-ty positive that Laser Interceptor is the best.
