Give me opinions on this rd please. I spent 150 bucks on it. I hooked it up in my car today and kinda drove around seeing if i could get any alerts and didnt really get anything. Ive got this return thing on so if i dont like it can return so tell me if i should and what other kinda of better detectors i could get for 150. I was kinda frustrated at it tonight already though cuz there was a huge wreck tonight and im supposed to recieve safety alerts or whatever and i didnt.
