Magnetic fastenings are very practical.
The filter fits perfectly on my PC screen and I like the magnetic attachment, which allows me to put it on and take it off very quickly. I chose to add the small plastic supports at the bottom of the screen, which are slightly visible but ensure better adhesion and stability of the filter.
It comes with a carrying case and does the job well. The view is greatly reduced for someone sitting next to you, on a train for example, but the filter does not interfere with the person using the computer.
It reduces the brightness of the screen, which is comfortable for the eyes but needs to be taken into account for certain tasks.
