It does what it says on the tin!,
This review is from: Expert Shield - THE Crystal Clear Screen Protector for: Panasonic Lumix *Lifetime Guarantee* (Panasonic Lumix TZ10-TZ30 Crystal Clear Expert Shield) (Camera)
I have attached a number of protective screens to smartphones and camera screens in the past, but this is the first time I have managed to attach a protective film to a camera without a single bubble and without a single speck of dust to spoil the effect. And as far as I can tell so far, the Expert Shield does not diminish the sensitivity of the screen in any measurable way. It remains to be seen how it fares over the next year or two but, so far, I say: Bravo.
