The glass is now already more than a month on my phone (Samsung Galaxy Note 3). It meets the required quality characteristics of me without restrictions. It is precisely tailored, very easy to install, resistant to scratches and the haptic feeling is more comfortable and higher quality than in a protective film. The operation with the S-Pen is also pleasant.
The price is reasonable. If you go to the local electronics retailer and see what there is in the range protectors at the price of EUR 10 offered, then one soon becomes clear that the Amzdeal-resistant glass is a great, affordable alternative.
