It is easy to install. Even if you are running the first driving lane on a three-lane national highway you can firmly confirm the car you are passing from the right side. Since it can be seen far from the genuine mirror, there is a sense of security as driving. A point to worry a little about may be a mirror depending on the angle when opening the door of the truck to the full open. However, the size of the mirror is exactly good, and the auxiliary mirror on the right side is too big and I think that it is about this mirror because it is difficult to see when turning right.
