in my opinion Boxwave makes the best screen protectors, I have used these on three different smartphones now. I have tried the Zagg and bodyguardz screen covers and didn't like the fact that they bothe have a grippy surface, the Boxwave screen covers feel like you don't even have a cover on they are ultra smooth and as slick as the screen itself.
