Title: It works
Review: I travel constantly and need to work on confidential documents on the plane. I first started using this product when I was working for a leading global management consulting firm - these laptop screens were basically required for all consultants and had been well vetted against alternatives. Since changing jobs I bought my own filter and recommend it to my colleagues as well.This product quite effectively makes your laptop screen unreadable to anybody not sitting directly in front of the computer, well enough that my immediate neighbors on the plane can't read what I'm working on. It does slightly darken the screen, but not enough to be a problem.You stick little plastic tabs to the frame of your laptop screen, and the privacy filter slips into the tabs. The screen is very easy to slip in and out, and the tabs themselves can be quite easily removed (but not re-used once removed).Highly recommended.
