I have been using RMR'S scramblers for over 20 years now, I currently have to Judge and it's about 3 years old now so I have just ordered the Judge 2.0, it will be nice not to have all the false alarms due to new car electronics , oh one other thing, they do work, I travel 100 plus miles a day to work going through all kinds of speed traps the only time I have got a ticket since using RMR was due to me not responding to the detector going off out in the middle of nowhere at 4:00 am with the only sign of a car was about a mile ahead of me, he pulled over and turned all his lights off just over a hill and got me doing 15 over, so no false alarms will be great! Thanks! JMP
