Review on Car Sun Visor Extender with Anti-Glare Day/Night Sun Blocker for Windshield - Enhances Driving Visibility and Safety in Cars, SUVs, Trucks, and Trailers by Ronald Duguay

It looks like a great idea, and to some extent it is. Who hasn't looked through the windshield at the sun on the horizon with their visor down and almost gone blind? Or do you feel the sting of an endless line of large trucks with their headlights on as you drive along the freeway at night? This invention solves both problems. You can use a gray flip-up "sunglasses" panel to filter out the sunset road and a yellow one to soften the headlight glare at night. directly on the driver's visor. However, there are problems. On the one hand, the thing is relatively thick. On my pickup, the visor doesn't fully collapse until it's in place. Second, and this is a problem, the block is mounted on an adjustable, ribbed slide. Maybe it's just mine, but it doesn't stay where I put it. Mine keeps opening so the entire assembly on the visor is misaligned and wants to fall off. I'll tape it up, but that might cause more trouble than it's worth. I like the idea but 2 stars for those issues.
