I drive a Ford with thick sun visors and these work wonderful. I have had several of the plastic ones in the past and they always broke. These are 6 months old and holing up well.Works perfectly for keeping my sunglass and reading glasses safe in my truck. I would recommend.I used this product for some months but decided to get another type of glasses visor holder because I found it impossible to add or remove my glasses from this holder with one hand. The mechanism that holds the glasses in place is very difficult to open with one hand since it actually must be lifted and held up (there's no sliding involved) and the glasses removed. I think it's dangerous to take both hands off the wheel, however briefly.These are a great looking and decently made set of sun glass holders. I would give a better review. But the foam that is supposed to hold your glasses is very soft, your glasses will slide in side of them. Mine have popped out.These clips are well made. No cheap plastic that breaks after a few uses. I am constantly changing from glasses to sunglasses, so they get a workout. I am very very happy. Wish I had these years ago.Great productI have two of these for my cars. They are nice clips for holding sunglasses on the visor. That way they are available whenever it is a sunny day. Also, no more sitting on my glasses.I gave an average rating because even though it’s sturdy, it’s a bit difficult to remove the sunglasses off with one hand while driving
