For a $2-3 product I was not expecting anything from this, but It's pretty good actually. It compares to some much more expensive ones. The flexible temples with rubber are great and comfortable. I'm a big headed guy and the flexibility of the temples are good enough. The blue lenses are also comfortable. It provides a clear view and things become a little brighter. But if you are working with colors, it will make colors a tittle bit different, so avoid using colored lenses when working with colors. But overall this is a great product.
