This little bit of kit is an absolute license saver, I avoided 6 potential traps in one 1500 mile tour. I'd read all the reviews both in print, and online, and this is consistently the top dog of all detection devices, so I made the purchase.

Now, some five years later I am still loving the V1. On my Z8 I now have it hard wired from the fusebox, the cable runs up the windscreen, inside the screen surround, and comes out in front just by the rear view mirror, allowing me to clip my V1 unit onto the drivers side sun visor. I really like this way of attaching it because it allows me transfer my V1 unit quickly between all my cars.

I've now done eight years with the V1 in my Z8, M3, GT3, both Lotus''s and even on my bike, and I have not got a single speeding ticket in all that time. I'd say it has saved me from jail a dozen times, and fines maybe several hundred times. It is absolutely worth its weight in gold.
Please don't think I am some tearaway hooligan driving like a nutcase in urban areas, I only go fast on the open, deserted back roads of CA, NV and AZ, when there is no one around, and it is safe and clear to enjoy the ability of our cars.
