    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

  • I've 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!
