I think my whistler and others I would assume have a major flaw. The threat priority does not work. Here is the senario, there is a spot by me that has a x-band flase and a little later (300-500 feet) has a k-band flase. Well the whister will pickup the x-band false but when the k-band comes into play it never alerts to it, only the x-band. On my bels, they will pick up the x-band but once the k band comes into pay they will switch and alert to k-band. The V1 the same thing, it will see the x-band but once it sees the k-band it will also alert to that. This I think is a very serious threat to whistlers because if a leo is hiding with a k-band gun the whistler will never alert to it, it will just keep alerting to x-band. This in my eyes is an even more serious threat then the ix locking something out, becasue I drive by there multiple times per day and it has never once alerted to k-band. The only way to get it to alert is to turn off x-band.
