I went for one of the gadgetshieldz.com clear skins.
I gave up trying to get the side pieces to sit correctly.
I didn't bother with the battery cover option as it would not look right on the textured finish.
In the end I just applied the front cover.
My thoughts after a couple of week usage.
It marks up when using the stylus (which I do a lot) and doesn't heal.
I have not used the stylus for a week (on purpose) and I can still see the words I wrote previously.
The overalll size could be improved, it is approximately 0.38 mm too narrow all round and you get an extra lip which is very noticeable when swiping.
Just my tuppence.
