well on one occassion I was the passenger when we were nailed from behind, the guy seemingly came out of nowhere while we were doing at least 90. My friend didn't have any detector at all.
and in two instances recently the laser went off and within seconds the police lights were flahsing and he pulled over cars ahead of me. But 9 times out of 10 the laser goes off and half a mile down the road I see the trooper on the left side of the road.

again, from the testing I've seen documented the V1 has had the best results from a trailing vehicle even though its very hard to catch but I've done it at least twice and someone else got pulled over.

as for the arrows I guess you can question the need for it but people like the cyrstal clarity of it. I'm sure if it weren't patent protected or required royalties every other radar detector company would offer at least one unit with a similar system. Escort, Whistler and Cobra lose enough sales by not having this that they would offer it even if it weren't they're preferred strategy.
