They're legal in Wi, but if you're spotted / caught with one, any chance of a warning ticket is lost...
I agree that speeding (over 10 over) is unnecessary. For every 10 mph over 55, your chances of dying in a crash, should it happen, double. That means if you're one of the yahoos who hang out in the left lane with your V1, going 85 mph, if you should crash, chances of dying is 8X that of a vehicle traveling 55 mph.
Speed is listed as a contributing factor in about 40% of fatal crashes nationwide.
Besides, traveling at a lower rate of speed can net you as much as 10% in fuel savings...

If driving slower is safer and economical, consider walking. Not only is it safe and economical, it is also healthy. In my own case I like to drive fast where it is not a safety issue for other drivers. It gets me to my destination quicker
As somebody mentioned they are illegal to use in Va and Canada, but so is speeding.
In my own case I never leave home without my V1 (Valentine 1). It has saved my butt hundreds and hundreds of times, both in my cars and on my motorcycle. No other radar detector compares to a V1 in one sense.
I was coming home (I live in the boondocks) around dusk one evening. My V1 went off and showed 2 bogeys in front of me. Eventually a state trooper passed me, and my directional indicator showed a bogey to the side and then behind me as he passed me, but I still showed two bogeys, one behind me now and one in front with my front directional indicator flashing (indicating the stronger signal). I kept going slow (Is there another cop in front of me?).
Within 30 seconds the second state trooper passed me and now I had an indication of 2 bogeys behind me. Before these cops were out of site they both had their victims.
With any other radar detector, I would have speeded up after the first cop passed by, thinking the beeping was from the cop who passed me, and would have got nailed. This was the first time I saw tandem cops, but the V1 did its job. No other detector gives you this kind of information. If you consider the cost of the ticket and the increase in insurance rates, the V1 is cheap compared to the other detectors.
You can see my car and motorcycles below. All are hard to keep under the speed limit.
