The complaint with V1 being to sensitive is not valid. You can adjust the level of sensitivity (in the manual) so that only known radar sources set it off. I believe it ships with the most sensitive option enabled. In the last 10years of use I've gotten so comfortable with the notice that I trust it implicitly.
