I have the tempered glassed Spigen
Its great, it feels as if you are using the actaully glass that comes with the screen. If I remember correctly after I had put it on the phone 5 months ago I thought it was better than the original screen. It doesnt have any marks after 5 month.
You have to be carfeul when you put it on thought because it you miss up you are out of luck and will have to buy another.
I used the go into the bathroom, turn the shower with streaming hot water and wait 5 minutes for all the steam and dust that is in the air to drop and then but the screen on trick.
