Radar detector did not chirp at all even when the officer was right behind me. He said I was doing 13 mph over the limit. I do not trust my radar detector anymore, it has saved me plenty of times so money well spent but I just can't trust it like I used to anymore, unless these officers are lying or I don't know what's going on. It did save me a week ago but this time it still didn't go off. Officer let me go, I had to rip the detector out or it would've been over for me. It was a great run! Not sure what I should do or if I should try sending it to Uniden to check it out? I am scared to send it back and have someone opening it up. I would like to thank Vortex Radar from YouTube for getting me into this niche! and the TX testers who always make great videos, will stay in touch with the radar community but for now I'll be taking a break!
