not nearly as well constructed as the factory mirror. plastic mount becomes weak when it gets hot in the sun and falls off. Also smaller than the original, and does not provide sufficient rear view for larger ford vehicles like trucks and vans.
This piece is absolutely junk. It's too stiff to move into position, so you end up working the mirror off the flimsy base. Once you do get it in position it vibrates so bad you can't see out of it anyway. I ended up throwing it out the window on the freeway. Now it's where it belongs.
