Review on 👀 Anti Blue Light Anti Glare Screen Protector for 21.5-inch iMac Retina 4k Display | Reduces Eye Strain for Better Sleep | Compatible with iMac 21 Models A1418 A1311 A1224 by Jennifer Miller

The protective film covers the webcam, no camera/network hole. Makes the video blurry and distorted. I don't know if it was defective or all but it was very difficult to put on, it was rolled up so it kept wanting to roll when I tried to put it on. There were a lot of blisters that I couldn't get out either. Update: So I got a replacement with a hole that should have been on the first one I received but now they sent me a DIRTY USED SCREEN PROTECTOR COVER. THIS MISSING PROTECTIVE FILM Rather, the carriers make a mistake when shipping used items. Protective films cannot be reused! I will not replace the same item again.
