In some numbered steps on the filter to ask, you know exactly which way to hold the filter, no risk of dust that embeds or touching the surface that it should especially not just touch, as happened to me regularly on other filters for other products (phones, consoles ...).
And besides, once installed, you do not have the feeling of having stuck anything, visibility does not change an inch and you do not have a big gap all around.
I definitely recommend this product for those who hate to ask filters, or those / those already posed filters but counted each time 567 air bubbles, the filter is for you!
Now my gamepad less likely scratches, and if I were to change, I take the same. Here, however, I will see if there are filters of the same brand for my 3DS and PS VITA ...
