Found the (almost) PERFECT case!

I've used it for a week now. The back is hard (though relatively thin) plastic, not TPU. The bumper offers a little protection. The fit is perfect.

Only con I have discovered is the power button is kind of hard to push...

Do you believe that the plastic will get stuffs and scratches easily?
