on New Years i took part in a very long road trip, it stated with the 5 hour drive from North Bay ontario to Guelph Ontario where i crashed at my place, the next day i then had the 10 hour drive from Guelph Ontario to Westchester NY, crashed at my gf's moms house and the next day me my gf and a few friends did the 20 hour drive to New Orleans. We brought along a radar detector because its a long ass drive and going 10-20 mph over the limit WILL save alot of time on such a long trip. Anyways the thing worked fine and i would recommend that they really only be used on long trips. If your worried about getting nabed they are only illegal in some states and when you enter said states they always make sure to tell you to turn them off (atleast on the way from Westchester to New Orleans). Like i said the thing worked great but i would only use one to shave a few hours off of a very long trip and if you plan to use one to drive at ridiclous speeds then your a moron (thats a general statement). Also along the way i noticed that a GOOD portion of this road trip had the roads watched by the air from helicoptors and the like, in which case im pretty sure a standard radar detector wouldnt work worth beans (their were always big signs stating such, i love signs).
