For me, no.
Any change to the device, its touch response, whatever just doesn't feel right.
I'll take my chances.
Had the Invisible Shield on for a whole two days before I could not stand it any more!
The edges don't stick perfectly and there's a lighter looking effect because of that. Really noticeable on a space grey phone.
Easy to remove but what to do with it afterward? Can't store it anywhere because of the adhesive side. Perhaps sticking it to a sheet of parchment paper and trimming it. Does not matter I won't be installing it again.
The screen looks best without and since I get a new phone every 3-6 months but no problems. For those of you that keep your phones for 2+ years, I can see why you want to keep the screen looking best.
Different strokes for different folks like anything else.
I do have more concern with devices these days fusing the outer glass with the LCD. No cheap replacement!
