People do get a little passionate about radar detectors
My preference is the V1. It fits in well above the mirror.
I used to have it hard-wired but now I have the "Savvy" (so don't need hard wiring) and I have a "Concealed Display with Band Identification" on this
Valentine1 page.
People who buy the V1 typically really like the arrows that tell you where the signal is coming from. There are more expensive radar detectors out there but, in this price range, you can't go wrong.
If you can, buy new from Valentine One. If you buy an used one, it might have older firmware.
