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!
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.
This is my 7th K40 radar detector purchase – nice update to product and good service at Patrick BMW.
Every mile I drive in my Porsche is more enjoyable thanks to the K40 radar/laser system. I’ve been warned several times of speed traps in the first two months of it being installed.
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.
The Installer’s Attention to detail was incredible on my very limited production BMW K1 Motorcycle and the product itself has vastly improved the enjoyment and quality of my ride–It is a necessary accessory to have!!!
This is the 4th K40 system I’ve purchased – always worth the money!
Just a compliment on great service. Had concealed system put in my BMW 550ix last week. Received a call within days from Brian who acknowledged receipt of my registration and asked me to call him at my convenience to go over features and operations of system which I did. Brian was most helpful and provided an outstanding customer service experience! P.S. system works great too. Thanks
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 from 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
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. Not bad for a regular consumer. Just wondering when you will have a frequent customer discount card? Thanks for keeping us safe.
I came in thinking I would get another radar detector, but Bob convinced me to get the K40. The speeding ticket guarantee sold me. And I have not been disappointed!
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.
This is my second K40 radar detector. The first one I purchased in 2001 saved me from a ticket the very first day. I thought it was defective because it alerted me 4 miles before I saw a state patrol. This convinced me how well this product works! It has saved me countless tickets since then. Thanks for making a superior product.
“Chat with Lynette made me select the K40 unit over others.”
