Dunno if you've read the reviews on the X50 but they show it outperforming the V1. The V1 is nice though I just like the X50 better and I got the blue lit display to match my Jetta's lighting. BTW, it saved me one time so far from Laser, believe it or not. It gave me early enough warning to mash the brakes and he was on an overpass. He got the guy that was tailing me in the other lane. It's also get great coverage on Ka which is getting increasingly harder to detect. So far the best radar I've seen is the Stalker. Used by all of the CSP and I work on the CSP cars so I've tested them greatly. Just get what "you" think is sufficient for your habits. I drive 60+ miles "to" work and then back. Hence why I spent the extra $.
