Anti Glare Screen
Works very well for privacy and for eye protection. If you are standing beside it it is hard for someone to see your screen. I bought it for the purpose of my eyes. The screen protection was an added benefit.

Privacy Screen
Very hard to get specifics on item. Extremely hard to return trying for three days now.

Works well
Besides being a privacy filter it also works as a screen protector and the matte works as an anti-glare. Easy to install and fits perfectly.

Privacy is great
The privacy is great with this filter. Cannot see the screen when at any angle besides straight on. The only thing I wish would be better is the screen curls away from the monitor screen a little bit when using the tabs instead of attaching it to the screen. I didn't want to attach it directly to my screen as I am unsure when my IT department will be replacing my monit...

Exactly as described
Items were delivered quickly and by Staples own delivery team. The privacy screens do have both a shiny side and matte side to them they also come with both the tabs to slide the screen into if your computer has a set back screen and clear double sided adhesive strips which you don’t see unless directly looking at them or for them. Works great to keep screens private f...

Barely works
It's not completely private. If someone is standing behind you they can still see everything. The side view is a bit more private and blacked out. Not happy with the quality especially for that price. I don't get why this thing costs so much and does so little.

3M™ Black Privacy Filter for 18.5" Widescreen Monitor
They work great. Would love it if they were just a few cm's bigger. The notch is noticeable and doesn't go beyond the screen into the black area. It's a little distracting only because I keep wanting to move it but if I do the entire opposite side shows.

Doesn't work unless you're at a sharp angle
I tried this both sides. If you're standing to one side or the other it does obscure the screen but if you're standing directly in front of the monitor even if you're 8 ft away you can still see the monitor very clearly. The idea was that someone should not be able to stand behind me and see my screen. This doesn't work for that at all. Plus it arrived damaged. I'...

Such a difference!
I love this filter and the fact that not only does it protect screen privacy but also filters out the light that adds to eye strain. This new filter was installed in addition to new lighting in my office (the filter came first) and my eyes are SO much happier!!

Nice product
I really like the overall filter; keeps others from seeing my work but I wish the 2 sided tape would hold up. It is constantly coming "unstuck".

Seems OK not great
I ordered the wrong size so it didn't fit. But it still seems slightly shiny. Not as matte as I had hoped.

Screen Privacy
Perfect fit. You literally have to be right behind it in order to see the screen. Make sure you use all the stickers so you’ll have a perfect hold.
