Ok, had a chance today to Challenge my new 9500I against my wife's RX-65 and One K band Speed Sign.
Test Set up- One K band speed sign set up on a very long and straight road.
I drove down the road out of range of the speed sign and started testing.
Initial K band Report- Winner................. 9500I (almost by .2 miles).
I ran several tests, The 9500I always was well ahead of the RX-65. Also please note, when this test was done, Each detector was tested individually, not both on at the same time.
At one point, I stopped the car on the side of the road, the 9500I was alerting K band with 2 bars. When I turned on the RX-65, it reported nothing, zip, zero. I even gave it the benefit of being higher on the windshield, nothing......no alert.
Next test- The 9500I and windshield placement. I found that if I mount the 9500I, mid windshield(I have mine more towards the steering wheel, using the speed for my heads up display), the performance is almost identical to placing it high on the top of the windshield. I found no big performance increase mounting high. I did notice a slight decrease in intitial response with it very low on the windshield(almost on the dash).. however even at this level it still reported sooner than the RX-65.
Overall, I am shocked by the performance of this detector and I highly recommend any V1 owners to give it a try.
