So I will confine myself to the obvious side effects. Those who were - 1) a relatively ambitious but price, at least compared to traditional screen protectors and 2) a significant delivery, which allows the immediate application of the film, without further aids.
You have six items can be found in the packaging. Of course the film itself, an electrostatic paper, an alcohol wipe, a squeegee for bladder removal, a microfiber cloth and two small labels, which also are supposed to protect the home button from being destroyed later. Yes, everything sounds just fine, my many years of experience in terms of "bang-you-a-protector-on-each-mobile" makes me smile just tired though. Why? More is not necessarily much. Okay, the cleaning cloth with the alcohol may still be useful, but also a good protective glasses cloth from its own budget is. The cheap microfiber cloth contrast provides more Staubfussel, than I would like. Antistatic paper? Nonsense. And the small squeegee replace professional glue anyway with a larger credit card.
In the circle of my family I take about 10 - 15 screen protectors each calendar year on different devices. The procedure is always the same. First, a space must be found by the humidity is relatively high. Optimal is the bathroom after someone has showered. Which binds the dust in the air. Then the display is highly polished, usually with a high quality microfiber cloth. After a maximum of still air (small hand bellows) is used before the film glued and is spread carefully.
It is this sequence works very well with the film of real power, only the feel of the film is a bit unusual, because clearly thicker, heavier and more resistant. However, this also has the advantage that the risk of air inclusions and bubbles is significantly lower than in very thin representatives of this specie. In this respect, there is no reason to complain, the attachment is relatively simple, but within 24 hours the past bumps were gone. The formats and blanks fit exactly, the contrast and the color reproduction of the display is not adversely affected. The responsiveness of the touch screen changes if necessary in the nanosecond range, maybe but that is just a fallacy.
Conclusion: The tempered glass protector is easy to apply, relatively expensive, and protects the phone to follow up from influences that would display not survive under normal circumstances. I them go out in person that I Case probably can in the worst not choose, is made on which side my phone in my pocket when I will eventually run over by a truck, next to me exploded a gas station, or Chuck Norris attaches to single-handedly, I classify the purchase of a Screen Protectors of that grade but rather in the category "total over-budgeting" a. But the sense and nonsense can be known to be divided.
