I have one; and yes, I feel it is the best detector on the market. It gives you a lot more information than any other detector that I've seen, including direction, number of "bogeys" (radar sources) and the audio signal to me is pretty intuitive on when to ignore falses and when to brake hard. It is expensive, but the difference can be less than a speeding ticket and the resulting increase in insurance rates.

Hope this helps,
