I took this protextion silicone pouravoir my qwerty keyboard in QWERTY. (J ia a qwerty at work, so I have preferred to have the same thing at home).
The protection covers very well my keys (white al origin) and it does not see that there is sth on the keyboard. very pleasant to the touch, and the keyboard is moin noise now. Genial, do not move, easy to clean, no complaints.
