Query: Highly recommended

I use this filter at work as I am in a cubicle and frequently have sensitive client information on my screen. If you are not facing the monitor head on you won't be able to read it. Even clients sitting in my office can't read the screen! I've not had any major problems with it. It cleans easily, installs fairly quickly. I have some vision impairment and have not been able to use some filters as they make the screen difficult to read. Not this one. It protects privacy while maintaining clarity. I highly recommend it.
