Regarding the screen protector, I am fully satisfied. I have not seen any changes in color or sensitivity of the touch screen.
As is always the case with this kind of protection, it must be cleaned before the screen and then apply the film with calm and precision.
For me, not a single bubble between protection and screen. It's all good.
Regarding the stylus, it is not necessarily essential, but I admit that it offers a better grip than that provided with the gamepad.
It can also be used with a 3DS, but given its size, I do not take him with me in transport.
Regarding the cloth, I'm a bit skeptical. Personally, I find it leaves little "fluff" blue.
So I preferred to use another cloth to clean the screen before applying the screen protector ...
