Note:
It does take a while to learn how to use them - to train your eye to focus on the mirror properly so you can see. It also takes some time before you figure out how best to adjust the mirror so you can see over your shoulder if you turn your head slightly.

that there is a protective film on the mirror that needs to be removed before you use it! This is one negative about this particular product. Just keep digging on the edges with your fingernail and it'll eventually come up. Then the glass is spotless and clean and you should have no problem with the clarity.
