I have often encountered difficulties when they had to put a screen protector on one of my electronics. Between the dust, bubbles, protecting the dimensions, I had myself always resumed several times. So I was expecting too much hassle again this time around. In the end, I have not encountered any problems. The dimensions are perfect. The cuts to the sensors, the 'webcam', the speaker are perfectly positioned and 'clean'. No bubble. The placement was perfect and fast. No impairment of sensitivity or brightness. More expensive than the protections made in ebay, but without comparison. Very good product.
