When I work from home, I sometimes need to protect my work from the eyes of others. It works well. You can also use the tab to make it removable if you want to share your screen. This goes well with my Dell Latitude 5590 that my job provides me with. It was easy to install, although I don't remember seeing any instructions. I've used this type of protection before, so it was easy for me. I usually have trouble using them on touchscreen laptops, but they work well with regular screens.
