TLDR: My giant iMac was hurting my eyes. I installed this protector in 2 minutes and now I can use my mac without an issue! Because procrastinating while WFH is a thing: I use my computer for most of my work, which means that I do a lot of staring at the screen in any given day; say... between 6-9 hours depending on the workload (or procrastination). I recently decided to upgrade my WFH situation and purchased a monster of a machine, with a matching monster monitor- the 27" iMac! Well, maybe 2 hours into working on it, my eyes were BURNING. If I had to describe the sensation, it was confusion- why on earth were my eyes on fire?! - and severe disappointment. After recovering from that mess, by looking away from the giant monitor for a few hours (and by reading -gasp- papers on paper!), I tried getting back to work on the machine. The burn came back. I came to realize that I'd been using a matte screen film on my previous computer that I use without a problem, so I got to work and typed "iMac 27 screen matte" and "27 inch monitor protector" onto Amazon only to be met with a myriad of confusion! Big pieces of plastic to put over your screen, silly covers that say to keep your hands off my mac, a privacy filter... the list goes on... I got everything BUT a straightforward and budget friendly solution. I wasn't interested in shelling out nearly 100 bucks for a screen protector, thank you very much. So I measured out my screen (width is ~23 inches) and searched for 23 inch screen protector, and BOOM out came a few viable options. It was so nice that once I found this listing I was able to use the dropdown menu and select for a 27 inch film specifically. This particular provider gave me 3 films for about the same price as others offering only one or two films. I decided 3 is a magic number (3 tries to get it right) and pressed the order now button. I got the giant box just today, I eagerly wiped my screen with my own cleaner (since the one included can at best wipe a phone screen.... haha!) and got to work. I used scotch tape to adhere the top edge of protector to the monitor so as to aid in aligning the monster. Once I got the alignment that I was happy with I kept the scotch tape on and started peeling the sticky end while working to keep the film from moving with the scotch tape. It was a little effort but I was done in less than a minute. Then I scraped away at the bubbles (gently) and decided I could live with 3-5 smaller bubbles, they're completely unnoticeable when the screen is on anyway. I peeled the top protector and viola!!! I guess one was all I needed... but it is great to have backups! I've been using my computer for 2 hours now and I feel nothing of the old pain. The text is just as sharp (in my opinion) and I can finally get work done. Matte screen for the win!!! Ok... back to work now, I suppose.

Superb product. Just follow the instructions and attach slowly.

Easy to use and it really helps improve you screen by blocking the glare. Very happy with it.
