First, because the jammer does two things I believe they are illegal everywhere (in the U.S.); I know for certain they're illegal in Australia and most of Europe. Those two things are: 1) Knowingly interfering with the transmission of a licensed device (aka radar gun) and 2) transmit a signal, which requires a very specific license for the bands on which it works.
On the mounting questions, I'm awaiting the elimination of a car in our family but expect to have an Escort to try the mount. I've looked my bike over and there seem to be three main options:
1) In the windshield above the dash
2) In the ram air
3) Under the cowl
The latter option is dicey in case either the suction cups come off or I hit a big bump and the forks compress a whole lot. The ram air option has performance implications(?).
I had planned to use an earbud for knowing about the fuzz since I actually don't keep any eye on the gauge cluster for the majority of my rides and so would need the audible alert. Also, the detector won't notice a shot from behind either, so that's something to be concerned about.
Not sure if you've seen a V1 but they're quite a bit bulkier than the Escorts so you should take that into account. Also, their main advantage, that I've noted, is that they indicate the direction from which a signal is coming and in the case of a bike, as I noted, you'd never get a rear-sourced signal.
