I have several friends with switches and they all choose what are called "glass" screen protectors. They all have blisters and trouble getting the damn thing to work without them. The great thing about this screen protector is that the installation is virtually invulnerable to idiots. You set up where you want, then just shoot the bottom half of the device once. This is key because it allows you to apply pressure in the same direction as your shell, which will get rid of any bubbles as you go. Thing is, there are no bubbles because the fit is so snug it literally sticks to the screen, a light rub with the edge of a credit card and all is perfect. Then you do the other side. I have no blisters and only had to do this once. This will protect your screen as well as any tempered glass screen IMO. Highly recommended for ease of use and results.
