"This is the 4th K40 system I've purchased - always worth the money!"
--J.F. Steger - Dubuque, IA


Douglas F., called our K40 Consult Line at 800.323.5608.  Douglas was moving a radar detector that he has had since the 80's, to yet another car. He wasn't sure which system he had so we had him describing components and wire colors.  Douglas is perfectly happy with the system, says it has saved him countless times.  He just needed a wiring diagram for it.  Well, we emailed it to him within minutes.  This was his response:


"Thank you Lynette,  I didn't realize I have had the K40 for that length of time.  It's reassuring to know I bought the best from a company that is still around.  I don't think I will need another since I am 68.  It may be time for me to slow down."

Thanks again!"
--Doug F. - Decatur, AL

"Hi Stuart",

"We haven't talked in a while, but I thought you might like to know that your laser system saved me last week.  I was on the Mass Pike headed towards Boston, about 5 miles outside of I-495.  I had jst broken through a traffic bottleneck and was completely alone and exposed.  My speed was 95 MPH in my E90 M3 when the laser alarm suddenly sounded.  I immediately stepped off of the gas and onto the brakes.  Ahead in the shadows, at the side of the road, was a Mass State Trooper.  I passed him driving 65. -No Tickett!!"

"The radar detector as alerted me countless times to speed traps in New York.  This Mass Pike incident was noteworthy because Had I not had the laser alarm and jammer, I would have been ticketed for sure."

"Your system worked perfectly! --Thought you would like to know."

"Best Regards,"

"Dear K40 -

I was test driving a Porsche at MotorWorks in Barrington, IL yesterday, and when discussing pricing for the vehicle, I inquired about a K40 system.  They handed me a brochure on your new RL Series, which sounds great.  The part of the brochure that made me laugh was the testimonial form the guy on his "Third K40".

I purchased my FIRST K40 when in high school for my Olds Cutlass Supreme.  It took me months to save up the money.  Ever since then, I have put K40's in all the vehicles I purchased as well as my work trucks.

1.  Cutlass Supreme
2.  Merkur XRI
3.  Cougar
4.  Cougar (1st totaled in accident)
5.  Ford Expedition (work truck, mobile veterinarian)
6.  Jeep Cherokee (ex-wife's work truck)
7.  Dodge Ram 350 (ex-wife's new work truck)
8.  Ford Expedition (2000 new work truck)
9.  Cadillac Deville
10.  Lexus 470
11.  BMW 530 (fiance's)
12.  Ford Expedition EL (2010 new work truck)

So, the RL360 will be my 13th K40 system purchased.  No bad for a regular consumer.  Just wondering when you will have a frequent customer discount card?  Thanks for keeping us safe."

Sincerely,
-- John J. Hanover, DVM, Cary, IL


"After having owned an RD850 (since past down to my daughter's Scion TC) ((one of the most preferred cars to radar by traffic enforcement officials)).  I have to commend your engineers on an outstanding job of designing the RL100.  Regardless of the sensitivity setting, when it alerts me, I know without a doubt that the above mentioned are in the area.  This from a driver with 43 years of driving experience going all the way back to the FUZZBUSTER days.

Thank you K40 and Audiodriven"

Thanks again,

On our service:

 

"Dear Steve,
I would like to thank you personally for helping me program my RL360 radar detector and laser system on my BMW over the phone.  When I originally picked my car up from the BMW Dealership the system beeped constantly, even just leaving the dealership parking lot.  You took the time, called me back and you were very helpful in programming the system to work with my BMW's Blind Side Assist.  Now, I love my K40 system!  When it beeps, I know that there is police radar.  I will recommend you and your system to everybody.  Again, thanks for your help."

"Job well done!"
"With best regards,"
--Dr. Rolf Haag

 

"I am very happy with the performance and exceptional level of customer service offered by K40 and my local dealer!  They took care of my every need and having the ability to have a hidden radar detector with laser defusers makes driving my Porsche all the much better without worry of the officer around the corner waiting!  Thanks Steve for all you've done to make the purchase of my new K40 RL360 one of the best decisions I've made for my Porsche.

“I couldn’t have been more impressed when I called K40 with questions. Your consultant answered every question, asked me another dozen questions about how and where I drive, and even inquired about my kids driving the car. All-in-all, it was an excellent experience and the results have been affirmed by my K40 saving me from at least three tickets already!”
-- David L., Pittsburgh, PA

"Lynette (K40) and Stuart (Performance Electronics, NH) - Just wanted to drop you both a note and say thanks for taking care of my detector problem. I have been out to our California home and now have used the detector enough to know everything is working great. I must say, you both know all about making the customer happy. Thanks for making sure that I am a very satisfied customer. I know where to go whenever I need help in the future. Feel free to use me as a reference. Well done."
-- Bill S., Boston, MA

--Michael R, Denver, CO
Installed by Stevinson Imports Porsche/Jaguar

"The K40 units installed in my cars are just what the doctor ordered to maintain situational awareness on city, country and highway roads.  Considering the amount of miles I've driven in the One Lap of America, to and from road courses for HPDE's, K40 has kept me ticket free over the years.  I am more than pleased with your products, technical support and most important, your customer service"
--Rudy A --Chicago/Florida
Currently owns 8 vehicles with complete K40 radar/laser systems

 
"I haven't used a detector in many years.  As midlife rolled over me, I gave heed to the need for speed and a Shelby GT500 came into my life.  Along with the car came a K40 RL100 GPS portable radar detector out of necessity.  It's very first task was the famous Cannonball Rally.  The K40 RL100 caught over a dozen situations and gave warning in the perfect amount of time.  Others were slowing a mile from the actual need but the K40 was always right in the sweet spot.  Illinois has Ka band with cameras on construction signs, laser on every police motorcycle, and a real need to generate revenue.  The performance of the K40 saved me thousands in contributions to various states and municipalities!  Thanks to the entire K40 team!"
--Greg L., Illinois

 

"I have had K40 radar systems in eight cars.  They have been fault free and 100% effective.  No tickets.  The alert warnings are also a great reminder on occassion when one is driving too fast."

--John N Hackett M.D., LaGrange, IL


"Loving my K40! - I picked the K40 because it was able to be installed fairly stealthy inside and out.  I am also loving my K40 because it works like a champ and keeps me alterted to where the police are!  An essential tool for anyone who spends time behind the wheel."

 --Jeff S., Duluth, GA


"After using my new RL100 for three weeks I have to tell you this unit is amazing! After trying 6 different units over the years, I finally have one that works the way I want it to. The Quiet Ride feature is fantastic. I can set my minimum speed and let it go. If I don't hear it, I don't have to worry about it. I love the fact that when it does go off it tells you what band and the stength. The GPS also allows the unit to double as a heads up display so your speed is never more than a quick glance away. The RL100 is the best radar detector I have ever used. Period."

-- Michael R., Elgin, IL


"Absolutely Superb! This installation is on my 4th car!"

--HB Shea, Boca Raton, FL - 2010 Mercedes E350 Sport Coupe


“I have your product on my BMW, and love it. It allows me to drive the car the way it was made to be driven. I spend less time looking for speed traps and roof lights, and more time with my eyes on the road."
-- Tom W., Fresno, CA

“The range on my K40 radar detector system is way better than any radar detector I have ever owned. I was sold on the no ticket guarantee. The K40 has also provided 75% less falsing when driving in and around the DFW area. I don’t know it’s there unless I need it.”

-- Terry Lynn G., Dallas, TX

"I personally use a K40 radar detector everyday.  I find the system to be extremely accurate and easy to use.  K40 radar detectors have been a name synonymous with quality and workmanship.  When a radar detector company can produce a product that has stood the test of time like K40.  The choice is simple.  I will be loyal to K40 radar detectors in all my cars.  Thanks for making a product I can depend on."
