New member here, bought an X50 Monday to take on vacation. I had been using Cobra junk for years after having a Escort 4500 a few years back. Have to say, loved it on the trip, went from Cleveland to Charleston, SC and back. Ohio State Troopers...tough because encountered 3 using Laser but alerted me when I approached them. Another, one was driving the other direction and used K with plenty of time to slow down and one from behind with K. West Virginia and South Carolina, many encounters with State Troopers using Ka with plenty of time to slow down. Did not encounter any in North Carolina and took it down in Virginia. Total Count: 6 OH State Troopers, 4 WV State Troopers, 4 South Carolina Troopers, and a few locals in SC. All were using Ka. I was impressed and wanted to share my experience.
