Ovimir 23 Inch (Diagonally Measured) Computer Privacy Screen Filter, [16:9 Aspect Ratio] for Widescreen Monitors Anti-Glare - Anti-Scratch Screen Protector - (WxH:509mmx286mm)

I ordered this for my coworker who has the newest MacBook Air model (A1932, 13-inch). Initially, the product came with a dent in the screen, so I returned it and ordered another one. The second one came perfect, so I'm assuming the first one just happened to be a defective one and bad luck.My coworker was sitting somewhere, and I walked past her and wondered why she was looking at a dark screen. Then I realized it was the privacy screen doing its job! I talked to her about it, and she was pleasantly surprised at how effective it was. She can have the brightness turned all the way up, and it still works. She did say she has to be directly in front of the screen to see everything, but that's it doing it's job.A note about returning the product: the seller does not allow the option to send a replacement, so we had to refund and send back the defective one and reorder a new one. We didn't have time to wait, so we ordered a new one before the refund was processed.Great product and does its job, but 4 stars since we had first gotten a defective one.

I bought a couple of these to use on my 23" monitors at the office, and they're extremely effective. Looking at the screen from just a few degrees off-axis causes the screen to go almost completely dark.Unfortunately, as with all screen privacy filters, they're pretty pricey, but they were still some of the most reasonably priced filters I could find, and they don't seem to suffer as a result of their price.The installation was fairly easy with the double sided tape they include in the package. When installed properly, the tape doesn't seem to impact image quality, or even really show up at all, which is nice. It's a bit fiddly to get the tape up off of the sheet and applied to the monitor, but it only took a few minutes.I'd happily buy these again if I needed screen privacy filters.

It’s pretty good. At first it seems like the screen is dirty but after a while you get used to it and see that it is not and it’s just the protector.

The only very small knock is that the bottom does stick flush. Beyond that, I am extremely please.

It works as expected. The gap when closing the lid is not to my desire however there isn’t much room in the lid design left. The factor screen face is nearly touching the keyboard.

I bought 2 of the 19" 5:4 privacy screens, used on Asus VB199 monitors. They are too big, and I had to push them between the display and the frame (around the display).The #2 film does not pull with the assign tab, and you must pull the privacy screen out to take it off.The privacy screen, is not great, you can see the writing on the screen from 3ft away standing 45 degrees from the center of the monitor.I did not return them due to the hassle of packing them, and shipping back, but I will not buy them again (for many more monitors that I have).NOT RECOMMENDED

This screen protector provides some help with the brightness of my screen, which is what I needed it for. However it does not do much for privacy. You have to be at a very sharp angle, nearly all the way beside the screen, before it appears dark to hide whatever you are working on.

This privacy screen works very well, I was required to get it for work. It does dim the computer some but not to much.
