i've already disabled X and switched to the extra sensitive Ka signal.
Haven't done my usual 25 mile commute yet, but I did get a chance to check on a false K spot and it alerted quicker and longer than my x50 ever has. So... first impression... apparently in that one spot at least, better K detection hah.
We'll see. The x50 is going back to Escort tomorrow. One month from now, I will decide which one is better.
I have it mounted high, btw... it definitely mounts better than the x50.
