Clever case, which has the advantage of not thicken the width S4, since the rear seat S4 sescamote to that of the case. Very well thought out. Hyper light. Weighed the S4 with its case on a precision balance, it remains lighter than the iPhone 4. Of course, this is not the titanium, this case will not be of great help in case of sudden impact. Avoid awkward for and "scabs". For others, completed its function and reveals in the small window provided for this purpose all relevant information: Date, time, network, battery percentage, wifi and callers with the possibility to win without opening the case or refuse the call. Also note that it is sufficiently robust and flexible to turn around completely and thus do not have a part of the case stuck to the cheek or neck. Best of all, it is rather nice and makes the same effect on fans who criticize Apple Samsung. What to say? After a week of use, this is always me too satisfied with my purchase ... And yet it was not won, I who have always been disappointed with the cases of the Iphone.
