The product and customer service is world class and among the best I have ever experienced. Lisa and ( forgive me, but I forgot the name of the first person who helped me how to use the system ). I had an inadvertent error during installation ( wrong product was installed 200 vs 360). One phone call and the issue was corrected to beyond my expectations. Kudos, keep up the superb work thanks again

Ive had the K40 system for just over a month with two (COVID) road trips under my belt. I really have enjoyed the technology thus far and I look forward to learning and experiencing more about the K40 Platinum 360 system. More to come... Safe and timely travels!

World class technology and world-class customer service. Could not be more satisfied. This latest installation was the second time for having K 40 systems on both of my vehicles

Everyone at K40 is amazing to work with. This is a company that truly puts the customer first, every time. Keep up the good work!

Great system so far! Looking forward to tuning on my frequently traveled routes.

Quality Installation. Best product of its kind on the market.

The is my 7th K40 and they work great!
