I am very pleased with the company that makes these protectors. Not only does the product it is guarenteed not just with this item but anything you purchase if you have not received it by due date. I was not given any hassle over it
I don't know if it's supposed to do it but all my pix come with a big blue hue. On both lenses I get the blue. I am not satisfied with the lenses if it's oil purpose is to do nothing but give one a headache.
