The films are very precisely cut and thereby fit perfectly.
I have it stuck in the bathroom because there is the least dust. Also, I have previously thoroughly cleaned using the supplied duster the display. Then I put in a half cup of water 1 drop of detergent, briefly stirred with a finger and it gave 1-2 drops on the screen and those distributed on the surface (keep away from all openings !!!). Then immediately launched the film from top to bottom and with a credit card out deleted the moisture and the bubbles and then gently with a soft dry cloth fixed and wiped dry. On the back I proceed in the same manner.
The films adhere absolutely perfect. They have good touchpad properties and do not reflect.
In my opinion, perfect price / performance ratio. I would recommend this film without restriction!
