how many years has it been .. ?? and it not only stops the glare but the reflections off the plain glass of this model of 21.5" iMac. When applying, do not be discouraged, since all air bubbles can be removed by lifting one corner at a time and laying flat from center out. Now. Later, at one point, i began to think that my computer was retaining heat because of this thing.. so i just made sure to turn the brightness down esp when the sun was on the other side of anything. Def glad to have made the purchase. i have no evidence that it does what it says it does, but losing the glare of these glass screen iMacs, this alone is worth it, and the sense that indeed your eyes are not as strained. Def recommended to all glass screen iMac owners.

This is a real pain trying to get the bubbles out. No matter what I can't get all the bubbles out. Its visually unappealing. Also note the product comes in a cylinder so it comes with a permanent crease.

El protector de pantalla cumple con las especificaciones, pero tiene pegamento en las esquinas, el cual es muy notorio al colocar el protector de pantalla, por lo que en las orillas se ve terrible. de haber sabido esto no lo adquiriria.

Works, I think, but a pain to install. Should probably make it more easier for simpletons like me who don't have good skills at installing it.

The good part about this product is, it works. It absolutely reduces the glare. However, it’s impossible to install it without getting bubbles on the screen. The video is not helpful. it shows the product being installed on an iPad. Much different than a 27 inch computer monitor. And the product advertised that it would fit my computer screen exactly, but it does not. It is too small, the edges are still exposed, which are very reflective. finally, the protective screen arrives in a tube. Which means when you receive it it’s all rolled up and to unroll it and have it sit flat on the screen is very difficult.

We needed a replacement square screen for our office. Only a square screen works with the program we use. This screen was easy to install and prevents glare. Just what we needed and for a good price!

Reduced the glare but made the screen so blurry, it is useless. I had to take it off right after applying it.

I want my money back! This is an awful screen cover. I took a long time applying mine, and the application is almost flawless. I got one speck of dirt under a corner. Despite a particularly good application, I can't read anything on my screen anymore. I strain my eyes trying to read text through it unless I blow things up to 150% or higher. This is the worst anti-glare screen shield I've ever used!! Honestly, what good is an anti-glare cover if I can't read anything after application.

We followed the instructions (which are not great, by the way), but could not get this screen cover installed properly. No matter how hard we tried, we could not get the bubbles out. And then the protective film that covers the 2nd side (which you're not supposed to remove until you have the first side installed with bubbles removed) started bubbling up as we were still trying to install the first side. . .making it literally impossible to install properly. It's going in the trash. If I could give it less than one star, I would.
