F FORITO2-Pack 21.5 inch Anti Glare Matte Computer Screen Cover, Eye Protection Desktop Screen Protector Compatible with All 21.5" Widescreen Desktop with 16:9 Aspect Ratio

perfect fit, but i still got a lot of air bubbles. I finally gave up on getting rid of the bubbles

The films were shipped in a cylinder holder. I purchased it for a 10.2 inches ebook reader. I carefully trimmed it on a paper trimmer. Unfortunately the film is not very sticky and it just does not want to stay flat due to being rolled in the cylinder holder. I have doubt it would stick on a 21" monitor. It is a little thick and I am not sure if it will work well on a touch screen. It just does not stick so I cannot tell. Just a waste of money.

Install was a little challenging, but definitely satisfied with the final outcome. There was a slight glare on my monitors in the mornings through our front windows, but this fixed my issue very well.

They are tricky to apply but they certainly have reduced the glare on my desktop. The directions were clear and the price was good. These things are a bit hard to handle, but adhesion is good. I do not believe that the bubbles will every go away no matter how much I push them out. However, they can't be seen once there is something showing on the screen, so I can live with them.

Hard tonput on by yourself and not get bubbles boy overall works great for anti glare and works great with touch screen

I found it almost impossible to install this screen cover. No matter how hard I tried, there were always bubbles that I couldn't get rid of.

one of the screens adhesive had come off so really there was only one screen. they came rolled up so when i put the one screen on, it had so many bubbles and would lay flat on the screen. i couldn't get rid of all the bubbles so i took it off and threw it out. kind of a waste.

If the surfaces are perfectly clean and you do it in a lint free room, it goes on crystal clear and there is almost zero glare. Good stuff
