I just bought a V1 off of Craigslist after doing a couple weeks of research on RDs. My general understanding was that V1's gave a lot of false positives. I've only been using it a few days, but virtually every time my V1 has gone off I've seen a LEO. I read another thread on this forum that might suggest the need for my V1 to be serviced. I'm using the default settings and the ka band is the only one to show a reading so far. I've driven past plenty of shopping centers the past few days without hearing a chirp. Maybe I'm looking too far into this, but I figured I'd ask for some feedback. Thanks in advance.
