Well, my real problem with the valentine 1 is that it would be item number two that I'd have to carry back and forth to my car every time I go somewhere. I've already had a $100 radar detector stolen, and a V1 is highly recognizable...

That being said, I've lived with and without a radar detector, and don't really find that I miss it. It can give you some advance warning, but it's nothing compared to just being alert.
