This is fantastic, especially at night when raining.
I am so elated that I purchased this glare-guard. I used to have such difficulty with oncoming headlights, and even with lights in my rear view and side mirrors. It was even more difficult on rainy and stormy nights.
What I especially like is that this glare-guard can be positioned different ways on the visor. At night I can position it so it minimizes the streaking from oncoming vehicles on the highway, and the sides of it even minimize glare from lights in my side mirrors. I have already recommended this to someone where I work and continue to tell others about it. I have a 1.5 hour commute both ways to work and this has made the driving in the dark a lot safer and more pleasant for me. I am very pleased! Highly recommend.
