Croakies Shade Dock Visor Clip
I had one of those cheapie sunglass clips that you push a button and the clip releases your sunglasses. Unfortunately, the button broke after about a year of use, which is probably better than I expected. However, it wasn't very friendly for one-handed use. As a wearer of prescription glasses and sunglasses, swapping one pair for another is most easily done if I can secure the other pair one-handed.
This product is perfect for this task. The glasses slide easily in and out of the Croakies clip and are held securely. Best of all, no moving parts or buttons to break. Dead simple construction tells me I'll have this product for a long time. Also, it comes with a clip that allows installation on the dash vents instead of the visor. I'm a tall guy and putting stuff on the visor is annoying for me. Also, the visor on my Jeep Grand Cherokee is too thick for the visor clip to work. Bravo Croakies on a well thought out product that is made in the USA. Thanks!
