This one visor truly removes the glare so I can remain seated comfortably rather than pulling on the steering wheel to get higher up in the windshield to let the sun visor cover up the space between it and the sun blinding you. It just clips to the sun visor and clear safe driving is your reward. Have you ever been stuck on a 2 lane curvy mountain road where the speed limits rarely get above 10, there is no edge with a little gravel to give you the hint you are about to meet your maker?Before I bought your glare visor I just accepted I couldn’t go any further and parked in a convient church’s parking lot with all the other drivers on their way home from work. In hind sight we should have met each other and played cards. 8 miles up and not an inch to park or pull over it’s a little before sunset and before the sun stops glaring in your eyes and the little 2 lane road is missing a few very important curve signs? I lived 8 miles straight up one of those PFFV roads planning for falling vehicles type of roads, more gravel than paved roads. I finally figured it out. Don’t try until sunset is over. The biggest problem with this idea is when it is dark and every driver needs to squeak past the others and no can turn off their high beams or they were sure to fall over the edge of the road many nights I chose to park and wait for the appropriate situation before I headed the rest of the way home. Going to work didn’t change the need for these glaring sun visors. Up or down your visor was such a glare buster. I tell everyone to get the biggest size you make.Here is my review. Being disabled with very limited reaching ability I would love to see a handicapped version. It is a wonderful product, eliminates at least 85% of the glare I guess. I am guessing at this. I still have to buy a helicopter so I can position my ascent or decent in the shade.
