After eye problems with my screens led to awful headaches over the course of just one week, I ordered Occushield for each of my three Monitors (2 monitors and one laptop). The eye issues and headaches ended as soon as I installed the screens and I could not be happier. I also purchased some computer glasses and most recently the iphone screen cover. Highly recommend this product. The install went well, I adhered the screen to the two monitors with the clear double-sided stickers and they look and work great. The laptop was a combo of velcro and clear stickers on the bottom. I have already recommended this product to numerous people.
