For now I am not disappointed by these shields! This is the first time I protections as easy to install without a single bubble !! It takes off a part of the support is placed in the corner and place slowly ... the film arises very easily and without the slightest bubble (I repeat myself but frankly it's happiness). Level protection it also seems impeccable. So we lose just the pleasant sensation of touch on the naked paperwhite screen, but at least the screen is protected ...
