Review on F FORITO 2-Pack Blue Light Blocking Screen Protector For MacBook Pro 16 Inch 2021 - Say Goodbye To Eye Strain And Glare! by Chris Shields

I did find these a little difficult to install because you have to be super precise, or else you get air bubbles on the outer corners :/INSTALLATION: It does not come with guides; luckily, there are two, but even being the slightest bit off cause the right top corner to be undone. You can see from the image that I was off by like 2mm from the bottom right causing the top right not to fully stick. which, yes, it's my fault, but a guide would be beneficial. Such as the tape guides that most cellphone screen protectors come with or something. I haven't replaced it because I am not too nitpicky about it, but if that sort of thing bothers you, ask for help with installation!QUALITY: I did think it would be much thicker than it is, but it is thicker than a regular protector. It's almost matte (kind of a vinyl feeling). As for the blue light blocking, I think it works? I honestly cannot tell much of a difference other than my eyes don't hurt after being on my screen for hours, so I guess it does as advertised.Overall, I think it's worth it if you can install it right the first time around!
