WOW! I can see tempered glass on my iphones due to dropping it and protecting it as it goes in/out of pockets, bags, mounted on/off my Harley, etc. I once closed my iPhone up with my trunk and the phone screen wasn't damaged......the tempered glass took all of the cracks, etc.
But for my 12" display.........I'll pass on that.
I do believe you when u say it works great.........thanks for the share. What made you get it though?
