My Brand new RX-65 didnt seem to work right but it was brand new.Well I got my first ticket in a long time . Radar went off like a instant on and I was nabbed. I asked the nice officer about instant on. He said no he had it on and I drove thru and got clocked 13 over. My cheap Sensoro Traveller never let me down. I went by same area with my new Valentine and had a 1/4mile warning on same cop at same spot. Yes Beltronics replaced with another one.I Ebay'd that faster than Dale Jr. at Daytona. I lost faith....oh well I vented.
