So installed this yesterday night. Front screen looks like it has some moisture and stuff underneath after applying. Had to take it out, spray and put it back couple of times. Back protection went so smooth n looks great.
This was the first time ever that I am installing a screen protector so maybe I wasn't good enough at the first go.
Relieved that I have some protection at least and can confidently place the device on the table without getting worried about scratches.
