Tonight I went out and half the reason was to play with it on the highway. Here the staties use X band. Well anyway the cops were out in full force. Going to my destination I got 3 nice X band alerts, 1 to 2 beeps and then some nice ramp up, bam..........full on alert and sure enough cop in the bush. Way home same thing but this time 2 nice X band alerts. I do not consider them saves since I had so much warning.
