What I like about the M8 is that the screen is flat edged, rectangle. No camera or speaker holes to line up with. So the installation was really easy for this. JLG includes a alcohol prep pad which has proven to me to be the best way to clean a screen for screen protector installations.
Another cool thing I learned about this Nano-t is that normally screen protectors come with two tabs/films on both sides to remove. But this Nano-t only comes with one film to peel off from the sticky side to put on the screen itself. The other side, which is what you will touch does not need to have a film to protect it because it is scratch proof and anti smudge.
A deal breaker to me for screen protector is if it works with cases. I put a SEIDIO Surface case on it, which is a slide/glide hard case and the Nano-t worked just fine. No issues at all. So I was relieved to learn that fact.
For kicks and giggles I even put it through a key and knife scratch test along with a sharpie test. All passed with flying colors.
There really isn't anything negative other than that at times the screen is too smooth and my finger tip will slide on the screen. Other than that its a really nice tempered glass screen protector.
TIP: They are having everything 20% through July 4th weekend.
