Ultra Matte rear is really nice - front not so much
I just installed the Ultra Matte set myself.
The rear is REALLY nice - really high quality feel to it, quite thick with a really nice tactile finish.
I didn't install the side bits because I'm using it in conjuction with the Apple bumper and they complement each other nicely IMO.
However the crystal screen protector is not so satisfying. It lifts very slightly around the button and earpiece (this happens with cheap protectors, but I didn't expect it with the more expensive ones).
It's also about 0.5mm too narrow, so that when the left side matches the edge of the phone, the right side falls a little too short. And this gap isn't bridged by the bumper, so there's a tiny gap along one edge. Not a problem, but enough to irritate if you're as anal as I am

And you only get one in the pack, so shifting it isn't really an option.
Doesn't really offer any advantage over the ebay 1.99 options IMO.
I have a feeling I'll be replacing the front with another protector before too long.
In summary: rear - excellent, front - meh.
Cheers
Pete
