I've had my V1 since last Thursday. Overall, I'm happy with the purchase. My only grips are that at night, being a fresh new owner, I can't distinguish if K or Ka is lite up! I suppose with time I'll just recognize the tones and won't depend on the lights.
Now, K range has been excellent to me. I pick up the two speed board signs well in advance when approaching the sun pass. My Ka range has been anything but impressive since my first lock on one. I've had about 5 or so. Only 2 of them being a threat to me though.
I have my radar mounted high, to the left of my rearview mirror. I can post a video later of me passing a state trooper running C/O Ka. I passed the cop initially with him on my side of the road. Range was weak, glad I was doing just 4 over. I got off the highway then got back on heading the oppote direction, took out my iPhone to record and I was still amazed by thr short response. It was a clear day and it was a straight view between me and the cop and the radar alerts moments after I've already spotted him again.
Is this normal? I've watched countless videos of V1s in use and range was MUCH better on Ka. My unit is brand new and of course 3.872 with settings at default besides X band off and was in advanced L at the time.
