I used to love my V1. But they are completely useless now that most cars have radar (not to mention your Model 3) so the detectors are constantly going off and crying wolf. Even if they can filter that out (and I have yet to see any do so very well), they are seriously hurting their range and response time to do so, not to mention the much higher noise floor of all the extra radar transmitters everywhere. Not to mentions 90% of cops use laser now. A good set of jammers, however, are still worth every penny. That said, most of what I use Waze for is for seeing things ahead like traffic and accidents, or just weighing different routes to take. I assume other parts of the country do not have the same problems.
