I have all 3 variants (S-sytle red, X-style black and turquoise transparewnt) ordered (one would like to change) together for an incredible 10 I now have 3 cases and 6 screen protectors. That's unbeatable. Now in the winter when the current outside temperatures I use the red, because it is the most sticky and softest model. On the sides nicely grippy grid and the buttons on the sides are very pleasant to use. That's at the turquoise and black not quite as soft, but certainly not stand out in the summer heat. The screen protectors are accurately and simply the best I have perfect plan to get. :-) Furthermore, very good response of the touch panel and no adverse reflection or the like. I am very satisfied and the set would buy immediately. (But now I'm first supplied ;-))
