If you want to give maximum protection to the screen of your HTC One M8/M8s, then this tempered glass screen protector is the best bet! The protective glass is made of scratch-resistant 0.3 mm thin tempered glass that is placed on top of the screen. If you follow the instructions below carefully, you will not get any "bubbles" on your smartphone's screen. The attachment is very easy, quick and no glue is needed. The glass also has the use of the touch screen - there will be no difference.
Can be used with all cases and cases!
When it is time to take it off, it leaves no marks on the screen either.
If your HTC One M8 gets dropped, the protective film takes as much of the impact as possible, so there's the best chance of the real screen doesn't break, only the protective glass, saving you the cost of repair .
As the protective film is made of tempered super glass, it will make the HTC One M8 feel a bit heavier, but this is offset by the fantastic protection it provides.

Note: The glass only cases the screen of HTC One M8. NOT the aluminium pieces at the top and bottom.
