For my part, the negative is the aspect that the Z2 with this protection.
On the one hand the notch that corresponds to where you insert the micro sim card was folded, making it "yawn" once the smartphone in the hull.
And secondly, that a lot thicker and heavier the phone design.
No opinion on the stylus and the films which I do not use it.
A good value for money then, but it will remain in reserve if needed.
