FYI... check with your state's vehicle laws regarding jammers. Jammers of any kind are illegal here in California. IDK about other states, though. If you're from out of state, driving in Cali, and you get pulled over, you WILL get a ticket for the jammer!

 

the valentine one is the ultimate radar detector, and it works, if your getting hit by laser or its nearby youll pick up a signal, other radar detectors are crap imo, jammers do not work! though there are laser plates and soon to be a special bra you can put on your car that will make you unreadable
