boxsterz,
I've had some experience with a V1, and I just didn't find the arrows that useful. If there's an alert, I slow down. When it's gone, I resume. For me, the arrows are not a must-have, just "cool", and not worth an extra $100.
My post was merely an attempt to correct the mis-information that keeps flowing, and to relate a real-world experience I had. It's obvious that many people have become passionate about V1's. Whether it's because of a great product or great marketing doesn't matter. I think they are a good detector, but I'm not a V1 cheerleader. Others are, and that's OK.
As you point out, most of the "tests" and forums out there are biased in some way. You point out two tests that rated the V1 as better, but I'm sure you know that there have been tests that rated the 8500 as the winner as well. Also, even if one of those sensitivity tests were actually run properly so the results can really be compared evenly, that doesn't mean those lab results will translate to the real world. There are abundant examples of that.
In the end, you pay your money and you take your chances.
