Don't remember the last time I was hit by a laser, but it definitely wasn't in Austin! KA is very widely used..
I love my Passport 9500ix for that, with GPS it blocks out all the chatter from false alerts, so comes in very handy in a city. Still use Waze on long trips out to know ahead when there is someone lurking
Had a V1 in my other car and it just drove me nuts due to all the false alerts..It probably can also do blocking etc, but I didn't mess with that since the Passport works out of the box..And I am planning to upgrade to the Max line.
