if you mean does it serves it purpose, then yes, definitely . helps in parking and cutting in close spaces as that's what i wanted it for
but i am not satisfied with the result as i was hoping and was told by JDM experts that the result would be same if not better then the camera from tracking world one(have you seen its result? its angle is wide enough and has very good result in night too) but its not. other option was to ask tracking world for camera and they were quoting 7k for front camera and that didn't seem reasonable
