This thing is alarmingly sensitive (pun intended!)
I got this for "Blue Streak", my acceleration boosted Tesla Model Y dual motor, after several close scrapes. I last used a radar detector since the 80s. Man-o-man have things changed. The new one is, as one would expect, an order of magnitude better compared to what I remember using, for roughly the same money I spent on the first one 40 years ago. It is feature laden, even without accompanying it with the available (for small cost) smartphone app. I got accustomed to it in no time. Granted, its not the top of the line, but neither is the price It is a far better than I was expecting (especially compared to the old days and considering inflation!) You can block out common frequency ranges used by radar/lidar sensors so that it doesn't false alert every time you pass a Porsche or Lexus. You can set it to "auto" mode so that it knows if you are on the high way vs. a city street. Even with the filtered city mode, I was recently alerted far more than a mile ahead of a K band speed trap. I could have spent more money on the latest and greatest model, but probably am just as satisfied with this mid range.

Paid for itself several times over in the first month on city streets and also road tripping.

Detection quality hadn’t let me down yet even after around 6 months of use so far. Suction cup mount is sturdy. I’ve gotten few false alarms compared to other units I’ve owned. Automatically mutes known locations like by a Walgreens or bank. On the highway it’s picked up Sherrif and state troopers as far as 5 miles out.
