I use the V1 and recommend it heavily. I believe they also have a program where if they make any updates to their system, you send yours in and they upgrade it for free and ship it back. I haven't had to do that yet, so i can't say for sure, but it was one of the selling points that I liked when I bought it.
Rethink the "false alarms aren't a huge concern" comment. I personally agree, I don't mind false alarms, it lets me know that if there is a cop, I can be damn sure it'll warn me. But you'll be surprised what the V1 will find out in the middle of nowhere. For example, one one of the long bridges I cross frequently, there is something at about the midpoint emitting X-band radar. Literally for about 10 minutes (at 70+ mph), without fail, I will hear "beep........beep.......beep.....beep...beep..beep ..beep beep beep beepbeepbeepbeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee eeeeeeeeee beep beep..beep...beep....beep." I look every time and I dont' see anything that looks like it would be emitting radar, but apparently there is.
I've also been doing a lot of interstate driving around in Texas, and I get hit randomly by a lot of Ka band from unknown sources. But over time you learn what a real hit sounds like, and it catches it in plenty of time for you to recognize the patter that you have learned means its a real hit.
