I just bought my first radar after doing much research..I spent 2x money compared to a friends cobra 9545 which actually falsed less. I even looked into excessive whistler false alarms threads and turned pop off. It took care of 60% of the problem. I am still getting many k and ka false alarms. Apart from auto quiet on and pop off everything is default settings. How are people saying they only get false alarms once in a blue moon??!! Overall as of right now I am highly disappointed with my radar... Commute in Houston TX if that helps.
