I ordered this protective glass because I did not want to pack in a fat envelope my S4. Therefore, I have now a 0.3mm thin case which is also available on Amazon and bought this glass. And luckily I had what it takes. Clearly one has no clever cover a very large chance of total loss, however, with this glass, it drops significantly. Mir is popped right on the first day of the S4 to the corner and over a small tear in the protective glass at the bottom corner, nothing happened. I guess it is really hard to destroy the original glass so. Thank you for this great invention. Aso scratches I have so far also no and the finger slides over it like the original, and you almost never grease stains on it. Thumbs up for this product!
