I'm using the best skin ever and I could not be more pleased with the results. It truly is invisible, no bubbles, no bad corners.
I put on the front skin too. It's not bad, helps a bit with the smudging.
The Naked look is so much more sexy too.
I should add that I have three cases and I can't stand the bulk. The I pit my rubber case on if I suspect I'm going to be in a situation where it might get knocked around a bit.
