I was driving along a side street in Kenmore this morning, on the way to dropping my kid off at school. All of the sudden, I got a Ka warning on my X50 from a Kenmore LEO coming towards me. I believe I was about 2-3 blocks away. My X50 was mounted low on the windshield. It then ramped up nicely as I got closer. I cannot believe the range on this thing!!! I am especially impressed with the warning tone compared to my other RDs and how it blends into a solid tone. Thanks again to Roy for the advice and recommendation on a solid performing RD!!!
