Privacy Screen Film: Anyone using it?

If so, how do you like it?
Does it greatly reduce normal viewing capabilities?

I got one from the apple store, an Agent 18 I think. It greatly reduced the clarity of the screen (to be expected) but it didn't even work that well. It would only black out on super extreme angles which by that point would impossible to read from. I was definitely not impressed, got rid of it in a week and never looked back.
