This product has a clear protective film on both sides to protect from scratches make sure you remove the film before using. Helps to use cloth gloves to avoid fingerprints, you can use nitrile gloves too.The dirty edges someone complained about is the adhesive strip that allows the blocker adhere to your monitor’s screen. This blue light filter works very well and helps reduce eye fatigue.Enjoy

I tried several anti glare shields before I found these. They did need trimmed down a little even though my monitors measured correctly. Best part is absolutely no air bubbles! The do take away from the definition a little but I don’t mind since this is my work computer. I also don’t like the tiny strip you peel away from the edges because it does leave a little residue. They do help with filtering bluelight but I feel there are others that do better in that department. But these are by far the easiest to install.

Feels like Saran Wrap, doesn’t stick to the screen and came in the package with wrinkles that won’t come out and make the screen look cracked. Horrible product.

For the gentleman that said it feels like Saran wrap, you could easily see in your picture that you did not take the protective 'saran wrap' layer off of the actual screen protector. Peel that off and everything will be fine. OMG.There's nothing wrong with the product, only the advertising of no bubbles. True, it has no bubbles but that's only because it only has adhesive around the border and does not seal against the entire screen like others.
