Good build quality. Many customization options to find the right viewing angle. The only problem is that when you open and close it, it unscrews. Of course, this can be solved by placing a small washer between the screw and the nut, and I wonder why the manufacturer didn't think of it.

Very easy to install. Wide-angle lens covers a large field offering safety. The mirror is smooth without distorting. Overall, it helped me a lot and at a very good price. I would recommend it.
