Review on MOSISO 20-22 inch Computer Anti-UV Eye Protection Filter Film with Blue Light Blocking for Diagonal 20, 21.5, and 22 inch 16:9 Widescreen Desktop PC LED Monitor Panel (Dimensions: 19.29 x 12.48 inch/L x W) by Jarrett Young

Installation was easy; It hung perfectly over my 27 inch monitor, covering the entire monitor and more. This makes it difficult to access my monitor's power button, but it's not a big deal. The packaging seemed really good, with nice plastic sheets covering both sides. Product and easily separable. Mine also looked brand new and didn't have the scratches or scuffs that some other customers have complained about. I also like the darker color my monitor seems to do. bright screen view - so if, like me, you prefer dark mode, you'll likely see a reflection of you and your room with it on the screen, making it difficult to see at times. I am considering returning this item as I don't want to turn off the lights and close the windows to reduce glare otherwise it's a great product.
