Got the 80 dollar credit, took a test drive today. Do not know how they did it but the 35.5 performance of the Redline is mind blowing. On and off axis performance is blistering, better by far than any other windshield mount I have used. A mode works well for filtering out k-band automatic doors. Have not had any 34.7 action yet but I am looking forward to that. So far I am very pleased with my purchase. Kudos to Escort!
