A Message from K40's President, Peggy Finley

I would like to start this letter the same way we begin every day here at K40 Electronics. In Appreciation.

Appreciation for each and every customer who has ever purchased our products.  Appreciation for our network of retail stores and car dealerships.

Many of our customers go back 30 years, with the introduction of the first machine wound, high performance CB antenna.  Some have just purchased their first custom installed radar/laser detection system and many have been driving with K40 protection for decades.  It’s important that you know each time you choose K40 products and protection, you are backed by a company of real people who truly care about your complete satisfaction.

Our network of retail stores and car dealerships are hardworking, committed professionals who have persevered within an ever changing and often unpredictable market.  Retailers who didn’t quit when faced with “Big Box” competition, who continue to reinvent themselves and offer white glove, personal service to their customers, thereby setting themselves apart from Internet resellers.  They offer the integrity and satisfaction their customers demand.  We started with you, we’re staying with you.  We appreciate you.

I am proud of the company we are, the products we offer, and the relationships we have forged.  You all matter to us.  And we are blessed to have you in our lives.

Peggy Finley
President, K40 Electronics

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.
