The performance of the RL360i radar was seven times the capture range of the police radar guns on all radar bands, X, K, and Ka bands used by police. It works as advertised! More…

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.

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 purchased a dual Defuser g5 kit with the intention of installing it myself with my UN2000 radar system I already had.  I talked to Brian about install questions and he convinced me to upgrade to the newest model and recommended Robin for the install.  Great advice!!!! Thanks Brian…Also Robin and his helper (son) Rashad were great to work with and did a fantastic job on the install.
