The installation was totally easy, done from previous experience in the bathrooms, if there is still evaporated nice after showering, then you have no specks of dust or fluff in the air, almost clean room conditions.
The fixing is done by aligning itself, the wheel sucks itself firmly on the screen, without any bubbles.
Should still produce disturbing bubbles dust grains can easily lift the disc again and remove it with the supplied adhesive tape the troublemakers.
The disc is very fit, has to camera and speaker a recess, thereby aligning's pretty simple.
Initially I had problems with a protective cover made of silicone, since the edge of the protective screen came up, the "bonding" is better after 2 days again now that nothing happens at the edges.
The promised "fat finger protection" is not as good as directly in the gorilla display from G3, on the first day we saw absolutely no fingerprints, but now you can see it quite clearly, but they can also be very easily removed.
All in all, a strong buy recommendation, especially since it seems that almost all the discs made by a manufacturer, the packaging, the description and the content always looks suspiciously identical from, even with xx times more expensive products.
The quality does not need much more expensive behind protective screens hide that has a lot more expensive Spigen as massive problems with the adhesion to the display.
