Negative Positive
Title: Worthless
Review: I was really hoping that this would solve the problem I have in the winter time (detector falling off from the windshield) but unfortunately it turned out to be a piece of junk. I agree with one of the previous reviewers that this can leave a permanent mark on your visor. It also eliminates the detection of laser (at least laser coming from behind since the sensor is usually on top of the detector). I saw a radar detector mount that you place on your dash, perhaps that works better?
Is the review positive or negative?
