It’s the second privacy filter I have had and I prefer this one by miles! It was easy to fit however I have a lot practice fitting our phones etc with screen protectors.
The privacy screen gives the screen a matt look which I prefer to the normal screens. I love that in my kindle that has a Matt screen as well.
So now to the privacy part of it.... I find if someone sits next to me they can’t see my screen however if someone stands right behind you they can obviously still see your screen just fine.
The only down point with this privacy screen is that the screen is darker hence you need to put the brightness up which reduces the battery life a bit.
