Check out V1's response to radartest.com at V1's site. radartest.com is biased, IMHO. I swear by my V1, it's never let me down. Once you get used to what all those lights are telling you, you'll wonder how you got by without them. My only complaint is that the band LEDs are all red and its hard to tell which tone you're getting at night at highway speed. My V1 has MORE than paid for itself in the four years I've owned it.
