Speaking from personal experience. I do a lot of driving (131K miles on a 99' G20). Mostly highway but a fair amount of city driving.
I will say that the Valentine One is by far the BEST radar that I have ever owned. Ive used Escorts, Cobras, Bells, etc...etc... The directional indicators are truly one of the best features, but its sensitivity and accuracy are smiply amazing.
For city driving, the V1 has three levels of sensitivity, the lowest setting only the strongest signals are reported. This is for all bands.
One thing that hasnt been mentioned about the V1. It will report multiple radar sources. For instance, there was a speed trap on I-40 going into Albuquerque one day, the V1 picked up the first cop (front arrow light up). As I passed the directional indicator went to the rear, and a second cop was up ahead a bit further. The front indicator lit up , the rear indicator stayed on, and the LED indicator read *2*. Nice thing about the V1, the strongest signal out of a bunch will blink, (when you get one, youll understand).
At Home Depot, Walmart, Staples, all of which are in the same shopping center, my indicator maxed out at *9* different sources...and BTW most of these were in the K band.
As far as making me a less *observant* driver with the V1, Id have to say that isnt so....keep in mind some radars are *instant on* and give you very little warning....so you still have to remain observant with traffic and the surroundings.
Another goodie that the V1 has as an option is the remote display. Simply a readout exactly like the radar has but you can mount anywhere, once activated the lights on the main unit shut off. Handy for night time driving when you dont want people following you when they see your little lights (we all have done this) I have mine mounted underneath the radio.
Another benifit, V1 will upgrade your unit when new technologies come out. They have been using the same form factor since day one.
Lastly: I will say to anyone...save your money and buy a V1 if you are serious about detection. No compass, no girly voice, no flashing led patterns, nothing.....but the accuracy and sensitivity I expect from a high end radar. Built specifically for one purpose and one purpose only.
