Are their any Radar/Laser jammers out there that actually work? If so which ones? And what would be a better investment buying a jammer or detector?

 

your profile doesnt say wher state your from and im kinda a redneckand dont know where u are, but jammers are only legal in certain states and cops can tell if u have one because their radar either reads some wacky number, or nothing at all so they can tell so depends on what state your in, id go with the jammer if u can and if not just the regual detector is the answer from me
good luck and cops are not cool

 

Are there any name brand jammers that are better than others?

 

Aklin is right... double check your state laws. If you get caught with a jammer or a detector they'll take it away and slap you with a nice fine. As far as the brand names that I've heard are good, I've heard a lot of good things about Valentine, pretty sure that's the name. I've personally used a Cobra in the past, about 100 bucks at Wal-Mart, and well, that hundred bucks is what allowed me to keep my license. If you're wanting top of the line be prepared to shell out anywhere from 300 to 500, sometimes even see them reach higher prices. What you need to do is hit some of the reviews on Amazon.com and other shopping sites. Get the reviews from people who have actually bought them, not the endorsed reviews you read about in Car and Driver and other such bull****.

 

well if anyone finds a very nice jammer post the link cuz i wanna check it out idk if its legal or w.e i ****'N HATE COPS and i could give less a **** if they no i have one as long as it saves my *** an i have one strike left

 

Don't worry too much about state laws, what you have to worry about is a federal law that prohibits unlicensed transmitters in the speed radar frequency. The FCC has set some very stiff fines, which will probably cost more than your car, and even jail time.
