I don't know if it's the rigidity of the film or the shape of the phone but the top and bottom edges never seem to stick right to the edge despite the very neat system for keeping the protector positioned while you peel off the bottom film. The matte finish is great for no stopping reflections but does show up finger grease so needs wiping regularly.
My first attempt was a disaster because this protector goes right to the edge and the sensor holes are also very precise. TUFF Skinz give you stickers to put on the side to hold the screen in X-Y position while you peel off the bottom film. Using the positioning stickers trick I was able to get a totally flaw free installation and the thinness of the protector makes it totally unnoticable which is what you want. It cleans up nicely and is resistant to scratching so I'm totally satisfied.
A nice snug soft case that fits very well and is very slim but the button covers are a bit thick and make it a little difficult to use the buttons, once you get the hang of the technique of rolling your finger across the buttons it's not so bad, certainly not bad enough that I'd bother getting a different cover.
