X200 Series 12W Privacy Filter 43R2470

[ComputerMinder]

I know that some use the 3M generic privacy filter. But I wonder if that X200 Series 12W Privacy Filter Part No. 43R2470 which I just saw on the tabook is easy to install and take off on every trip I make. That is, does it need peeling and slowly rolling over the screen like a thin layer, or is it something you can put on and off in a few seconds ?
