I am very pleased with the quality of this product
I purchased two of these since I was sick of my glasses and sun glasses getting tucked into any available open space in my truck.  Lens swap did send me a 3rd unit for free if I wrote a review.  I am very pleased with the quality of this product.  It was a bit more expensive than some other options, but after reading 100s of reviews on various options I do not see many of those problems happening with these visor clips.  I intend to purchase more for the wife's car.
