The difference is not immediately noticeable but after a few days my eyes are not as tired.

In this review I would like to 1) correct some wrong things in other reviews (or at least things that have changed by now and 2) take into account conditions that are stated by the to make the product work better.The conditions that are stated to affect the degree to which this product will work are 1) environmental lighting (it helps to have a well- lit room) and 2) the level of monitor brightness (the more dim you have your monitor, the more effective). This brings me to my first attached photo. You will not be in a better-lit room than the one that I have run my test in. It is lit by successional, bright LED bulbs and will be optimal for conditions that you will experience in class and office settings, but there is little likelihood of you replicating the conditions with warm lighting at home. The test started at 75% power (the second photo is 75% brightness, no cover). I then added the screen in the third (75% brightness, half covered) and fourth photos (75% brightness, covered). You can see in both at 0 degrees of angle the cover provides no hinderance to reading and may be easier on the eyes. However, also note the amount of reflection has increased considerably and glare may be more of an issue. In the fifth and sixth photos you can see that one must be at a considerable angle to have no visibility (both 75%, covered). Thus, overhead lighting is shown to be insufficient, as stated on the packaging.At a lower degree of brightness, the cover is noticeably more effective. Picture seven is at 0 degrees angle and has begun to show signs of difficulty on the sides, similar to vignetting (25% brightness, covered). Yet, when at a similar angle to picture five, the screen is still relatively visible, and you can still see the display of brightness. I did not test any lower brightness because it becomes unrealistic for day-to-day use, perhaps effective for times of highest security concern.Concerning attachment, 3M adhesives are provided, and 2 methods are given to the consumer. 1) You can put tabs on the sides, allowing the scree to slip in between the tabs and the monitor's screen. The first method makes the screen easily removable and is preferable. I was unable to try this method because the plastic siding on both sides of the screen is far too thin to accommodate the tabs. Using this method does make the screen reusable, provided only that you acquire more tabs. 2) You can put double-sided adhesives between the screen of your monitor and the protection screen. This method may be your only choice but has obvious drawbacks, including making removal difficult, trying to put it on a different screen, and losing adhesiveness when repeatedly applying and removing. 3) A third, and less viable, method that I opted for in the long run (which is not recommended by the packaging) is to simply rest the screen against the monitor. This is less of an issue on a laptop (which I use) because a backwards angle keeps it from slipping down. This method allows for transferability and no sticky residue on your screen, but it sacrifices some visibility at 0 degrees in the middle because of bowing. For me, the bowing is a worth-while tradeoff.TL;DR Yes, the screen has problems, especially for those with the deep concern for high security and for those who cannot accommodate plastic tabs on their monitor. However, certain concerns, like brightness and reusability, has not been addressed by all reviews and may (MAY) not be a concern for you. 3M adhesives work well, at least the first time it is stuck.

I’m glad I decided to buy this privacy screen. I take my laptop around town a lot, and sometimes I’ll see people looking over my shoulder, making me feel uncomfortable. It’s very easy to install, taking just a few minutes. Even though it blocks the view of other people, I can still see clearly. I highly recommend this, especially for such a great price.

I bought this product for privacy on airplanes. Alas, this screen isn't much of a privacy screen; you can still see things like credit card numbers from the center seat and even somewhat from the aisle seat if the laptop is on the tray table of the window seat. And if you're stuck in the middle, forget it; the people in the seats on both sides of you can see! Plastic sheet was tough to attach without it sliding off. And seller is not honest; peppers reviewers with annoying e-mails offering money to have critical reviews removed. Go elsewhere.

cumple para lo que necesito

Me gustó que fue muy sencillo de instalar, ajustó perfecto en la pantalla. Tengo la privacidad que buscaba y me permite trabajar sin importar quien esté a mi lado. Me encantó que trae un folder bolsa para guardarlo y una pequeña franela para limpiar la superficies

This screen just slipped over the edge of my computer screen - very easy, no installation required!

el producto me pareció de buena calidad. Además llego de acuerdo a lo acordado.

El tamaño es el indicado pero el artículo tiene un par de detalles:1. Los stickers que trae para fijar al monitor, son un poco difíciles de manejar y en el caso de la pestaña de sujeción, esta se rompió al colocarlo.2. El buen desempeño depende mucho de la luminiscencia y resolución del monitor. En mi caso, tengo un monitor BenQ HD 1080p y desafortunadamente oscureció muchísimo mi pantalla.A favor:La pantalla de privacidad cumple bien su función a partir de un ángulo de 20°. Eso está perfecto.Personalmente yo desempeño mi trabajo en un lugar que tiene exceso de luz del sol, así que ayuda a disminuir el cansancio ocular.
