I bought a cheap one over a year ago. Well last month I’m on a narrow country road and a guy in a 3/4 ton pickup with his mirrors extended hit my pickup mirror and broke his glass and my chrome mirror cover. Well he comes up and said “You hit me, I said nope you hit me”, when He looked and saw that I had a dash cam he knew he was guilty. It showed that he had about 18” between his tire and the edge of the asphalt. I bought a much better cam the next day.
