I hope my review will cover all the doubters out there.....I have a Lenovo Z400 IdeaPad touch screen. After doing my research I decided on the COOSKIN 15.6 inch Anti-Glare Screen Protector. I knew full well that my screen was 13.58 x 9.6 x 1.14 and COOSKIN clearly explains with a graphic that their screen protector protects 13.58 x 7.64 with a Monitor size being 15.6 in., monitors and TV's are always measured in their description on the diagonal. I knew my screen had about a 1/2 in. border around the actual screen (actual screen size is 12 x 7).If anyone has the Z400 touch they will know it is like glass, lots of fingerprints. I could not use my laptop anywhere near a window or outside, useless. I did upgrade this laptop to Windows 10 (they advise not to on this model) and there is a screen issue with brightness, Lenovo will not fix it. That means we have no control over our brightness, it stays at 50%, my laptop became more useless. I decided to get the Anti-Glare for these reasons, brightness issue, glare and fingerprints. COOSKIN did say that this protector does work with touch screen, I was skeptical, but it was cheaper then a new laptop, so I purchased, $12.95 vs. $1000.This item came in a very sturdy cardboard protective package, everything was sealed, clean and protected. No cracks, no creases, they even included a small sample you can test before trying the screen. (see pictures).I followed the directions, made perfect sense to me. I did have to clip one side (right) with a paper cutter TO MAKE IT FIT MY SCREEN. I laid my laptop on a table with the monitor laying flat. I propped the keyboard up against something for stability. I laid the anti-glare over the monitor with #1 INSIDE facing down, but before I did that I pulled back the plastic protector (cellophane) from the #1 INSIDE back about 4 inches. I laid that four inches down (left side) on my very very clean, dust free monitor with my left hand and with my right I was holding the cellophane underneath the anti-glare, both hands were stabilizing the anti-glare screen (this allowed me to use both my hands) so I can slowly pull the cellophane from under, with my right hand, while scrapping the screen with the blue plastic scratch card, with my left. If a bubble appeared I would just gently pick up the anti-glare and lay it down again while scraping the card. As soon as that section looked good I would pull some more of the cellophane from under the anti-glare and work that down until I got to the (right) edge, pulled the rest of the plastic cellophane off and "Wha La" it 's done (yes, sometimes I would switch hands so my right hand could work on the bubbles while my left hand was holding the screen in the air). After you get the screen on, peel off the #2 OUTSIDE cellophane and use your scratch card to get out any little bubbles you see hanging around.I have been using this anti-glare screen on my touch monitor for about a month and it works great with the touch monitor and no fingerprints. I sat outside at my picnic table and I was able to work all day with my laptop in a very sunny spot under an umbrella with absolutely no problems.Three reasons I gave this review. First, they sent me an email asking me to review. Second, everything I read about this product fit my needs and some more, I found nothing written about resolving fingerprints so I can tell you it worked. Thirdly, I had to laugh, a week ago I had a visitor who owns a small MacBook, I believe its the 11" . She brought me over the very same COOSKIN 15.6 inch Anti-Glare screen and told me I could have it or she was throwing it out. I asked why and she said it does not fit her screen, I could not stop laughing. Half the negative posts for this product are because the purchasers claim this product did not fit their screens. Cracked Me Up!!! I will be helping her put it on her MacBook.
