I have macular degeneration and spend a lot of time on my computer. this cover was very easy to install and I can not even tell it is there. My eyes do not hurt as they did quite often. Wish I had bought this sooner!

Really works!! I put instalked and worked for normal my 8 hour day min. Typically I get severe headache and eye strain. Literal eye pain. Today after using screen one day, my eyes only hurt a slight bit. Amazing and highly recommend to anyone that works on laptop all day! Only reason I didn't give it a 5 star is that the instructions were not very clear. The video has no sound, just follow along with the video. Just shows you how to put it on, not very helpful! I had to put it on and pull it off a few times due to bubbles. And if you see the picture there are still a lot of large bubbles that I cannot work out. Size is very close two screen size! Almost too much! I can live with bubbles for how much better my eyes feel!

Good with good explanaition of how to install

Does what it says it does.

Thank you, I have much less eye strain now and I love the little sticker slide to cover up the computer camera when it is not in use. It was about a 1/4 inch smaller than my screen, but it still works. I used it for a Dell Lattitude 3450.

The product came damaged with a bubble on the actual protector before I even installed it on the laptop. I am still waiting to hear back from manufacturer about a replacement.

Nice product. You must have things dusted well before application.
