This privacy filter does its job well. I've had it for a few days because a fellow colleague will constantly stare at my screen and read what I'm doing. He came back today and sat by me, instant frustration, "What the hell is this!". I instantly knew that he couldn't see.I have two problems with the filter - probably because little things tend to get to me. The gold is obnoxious, my fingers look gold when I'm typing with that side of the filter on. And there is quite a bit of reflection from the screen, i can see myself no matter what screen brightness I'm using.All in all, I give it an 8/10 solely for doing its job and my peace of mind.
