I have a sedentary job, so I spend most of my time in the office. I really don't like when my very inquisitive colleagues look into my laptop.
So I bought a ZM film here. It protects the info on my laptop from prying eyes: I see everything, but nothing is visible from afar. Very pleased because it has become much more comfortable for me to work. Thanks!
