I have stopped using a Tempered Glass since it interferes with the case and peels off, now I have applied a GadgetShieldz Screen protector since they provide a case-fit protector.

I do like the idea of the 360 degree protection, I worry about the exposed cutout bits for the headphone jack and stuff. My only concern is what is this made out of? If it's some sort of squishy rubber type it's going to feel like crap with the S-pen and leave marks all the time.
