I've owned all three rx65, x50, and now the V1. With the V1 in logic mode and with kband set to mute for the default setting of 10 seconds and the rear antenna set to mute for the default setting of 10 seconds I actually like the V1 better in the city than my x50. the x50 would alert me to the same doors as the v1 however I had to reach farther than with my v1 to mute it out completly. Now I have the bogey counter which is nice but can get crazy, but more importantly I have the arrows. so now I might be getting a door but I will its to my side and not pay attention, and just have a few inch reach to mute it out.
after owning the v1 for 24 hours and putting it through the ringer, 3 laser encounters, and driving past a Ka photoradar camera I can promise you the V1 significantly outperforms the x50 especially in Ka and Laser.
One thing I hate about the x50 is when you get hit with laser you get a default warning that keeps going. with the v1 when the laser stops it stops. Also today on logic mode I was holding the Ka photoradar with the rear antenna for 2.1 miles. And it was almost 2.5 miles with the front antenna.
Off all three I've owned I hated the rx65 the most it gave me tons of pop / laser falses for no reason. and the tones just annoyed the hell out of me.
2nd place is the x50 nice unit but the blue would drive me crazy at night, and the laser and Ka just cant match the V1. its automute was nice but I have no problem with the V1 once I adjusted it to my needs.
Hands down my favorite has got to be the V1. But only time will tell
