I live in a small city of 38000 people in northern wisconsin. I purchased my V1 probably 4 months ago (before my city got laser). Now I cannot go a week without seeing a cop but no alert but then laser goes off. Luckily I haven't gotten pulled over yet. I'm thinking I probably need to get a jammer now. I drive a blacked out 1999 VW passat and 75% city driving 25% highway. What would you recommend?
