I tried several detectors, even much more expensive ones. The R4 is my choice It’s upgraded tech has great range and filters out the garbage signals automatically or manually and is especially good blocking aggravating trash signals coming for other cars. And when it does get a legit threat it’s on it a mile away.
Other detectors have arrows, and that would be nice, but those can give off confusing signals. With the R4 range you soon get where you can tell by the signal pattern if the threat is in front, rear, or to the sides, (and the threat sounds are just cool.)
This little baby is solid, huge memory for storing mutes, will itself recognize and store a false threat location after a few passes, will pretty much be quiet as a mouse until approaching a real threat. At that point the direction is not as relevant as slowing down anyway. I live in a section that uses Ks and Kas, didn’t know this till R4 educated me, so I can’t turn off the K band, but my R4 will not sound a signal from another car like I found that others do. I don’t speed much but I will get liberal with the speed limit sometimes, and that has cost me hundreds in the past With the R4 you really feel like you have and R2D2 on your side.

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