I purchased this being sceptical about how well it would work. I haven't used screen protectors in the past as they interfered with the stylus, however, I'd heard good things about tempered glass.
It comes with a simple and comprehensive set of instructions, a small cloth and a wipe soaked with isopropyl alcohol and a squeegee.
Following the instructions, installation was very easy. You can see the screen protector sticking as you place it onto the screen, and the squeegee was not needed as no bubbles appeared, however I appreciate its inclusion. You can also easily remove this screen protector by sticking the squeegee under one of the corners, although I'm not sure if you can re-use it after.
It sticks well, and installation was much smoother than I had imagined. This screen protector did not seem to effect screen responsiveness in the slightest. The screen protector is very smooth, and the lightest touches with my fingers were still recognised, along with the lightest touches from the stylus, and pressure sensitivity appears intact.
This is much better than the plastic screen protectors which have a lot of friction when you try to swipe on the screen, and also become marked when using the stylus - plastic screen protectors can also wear down soft-tipped pens quite quickly, such as the S-Pen included with the Note 3.
Considering the ease of installation and the fact that the screen responsiveness does not seem to have changed at all, I am very impressed with this tempered glass screen protector, and would highly recommend it to anyone looking to protect their screen whilst maintaining screen sensitivity and clarity.
