On the V1, I am one firmware revision under the “Junk K Fighter and Traffic Filter”.

The good: arrows point out direction of signal, eliminate false alarms, heads- up warning of traffic cameraThe bad: suction cup does not sucks and keeps on falling of from windshield - very vexing, detection range is short, power cord is short

Naysayers will chime in and state that *really* the difference is $269 vs $649; I either spend $269 and get Junk K Fighter and Traffic Filter and hope it does the job, OR I spend $649 and sell the V1 to recoup costs.

You can add the Junk K Fighter and Traffic filter, but you’ll pay for it.

I already paid that many years agoNow, to get the Junk-K fighter and Traffic Filter, I would have to pay an extra $269 to get it

Highly recommended as long as you can remember to take it out of your vehicle EVERYTIME

If the software/app worked as it was intended, clearly 5 stars.

Alerts me for every K band I was going through until I cloud not make the difference between the real one and the fakes one
