5 of 5 R3 September 27, 2019
Reviewer: Anonymous Person from Sioux Falls, SD United States  
This is a great radar detector.  It has detected radar for me 2 plus miles out and has prevented me from getting tickets many times. Well worth the price.  The GPS is handy as well so you can mark radar traps on  your regular routes.  The customer service provided by this company is excellent.  You will not be disappointed.

4 of 5 Works perfectly September 9, 2019
Reviewer: david paras from Carpinteria, CA United States  
Just got it. Programmed to not respond to K band as in California they don't use it and it should eliminate the tons of falses that you get now from doors and cars with detection systems.

It works perfectly. It so quite and goes off only when Ka is there. Notifies me of red lights and warns me as I reach my marked spots (we've got some well known traps).

The only thing I would have like are the arrows. When it goes off, it would be great to know what direction to look for the person. Now I just slow down, but if it had the arrows would be perfect. Understand that the R7 does it and it's $200 more. I just wonder if I should have paid the $200, just to make my mind more at ease.
