Top critical review
OK, but not brilliant.

This screen protector goes a little way to providing privacy. However, although the screen contents are distorted, the view is not really hidden much at all. I previously had a Macally 4-way reusable privacy screen overlay. I wanted to replace it since it was getting a little tatty (only after about 18 months). The Macally overlay doesn't stick to the complete screen, like the Pro-tec, but is held on by six 5p sized adhesive buttons. On a black iPad, they are slightly visible against the frame, but it looks fine. On a white iPad, the buttons are clearly visible, but if you can tolerate that, it's fine.
The Macally overlay is fantastic! If you not looking almost directly at the screen, the screen appears black! Excellent! Precisely what you need from a privacy filter. Aside from the visibility of the adhesive tabs, there are two slight downsides. Firstly, because it is not stuck down over the whole surface like a normal screen protector, the edges are susceptible to being caught and it eventually looks a bit tatty (which is why I wanted a change). Secondly, because it isn't stuck down over the whole screen, dust can get between it and the screen. However, this is no real problem since the overlay is easily removed and replaced (it's reusable, after all), so the screen can be cleaned as needed. In fact, if you don't need the privacy most of the time, you can leave the overlay off, only putting it on when you need it.
Having used the Pro-Tec screen protector for a couple of weeks, I'm scrapping it and replacing it with another Macally overlay!
