I have been using the v1 and x50 head to head with daily driving for several days now.
The V1 flases quite frequently with laser...3 laser hits on the fwy alone during an hour drive...x50 stayed silent...we were in a rather rural area...no cops ever seen. Maybe from brake lights. During traffic in the city, it really is more common than i thought it would be. It is very very rear that the x50 falses with laser.
So far, I have found that neither detector alarms earlier than the other on a consistant basis. However, the V1 does hold on to alarms for a longer period of time....this is without a doubt.
The V1 continues to false much more frequently than the x50. Even on the fwy this is true.
My wife recently drove on a 200 mile round trip, and she took my Lexus with the two detectors. She really has no interest in these detectors what so ever, and really could care less about what Im doing...LOL. However, she knows how to work them both. Anyways, after she came home, she told me the V1 kept going off throughout the trip, and she ended up turning down the volume "becuase it was annoying". She does not speed really. But I found that interesting that the V1 was annoying due to frequent alarms without any cops ever seen.
I did ask her if she got hit with any cops, and she said on three occasions a cop was in the median, both detectors picked them up about the same time...but the v1 kept alarming after passing them.
Hope this little update helps. I really am looking forward to jammertests testing of the rev 5 x50.
