I agree. I feel just a bit conned by the radarspotters site. I simply wanted to register to ask some questions about buying my partner one of these radar systems, looking for impartial advise. Instead, I can't get registered, and get asked loads of probing questions.
Maybe it's just a site for getting people to answer their survey - definately a con. Steer clear. I did read through some of the posts, and it seemed a very bitter and twisted group of people - very strange. I guess there's some history behind their bad attitudes.
