The sleeve fits comfortably in your hand, the surface feels good, and the attachment to the S5 is relatively simple - you have to remove only the back cover and the back loose smartphone powerful and precise pressing in the sleeve until it locks completely fixed. The S5 automatically activates the screen when you open the cover, can be easily operated with open geklapptem back cover, and a recess for the Home button is also available. However, there are three negatives: on the one hand can the cover do not close properly, as there is neither a magnet nor another kind of locking mechanism, and it rattles so only half open around - in a crash, it would eventually rise and protect the screen in any way; also can not use the cover to the vertical or horizontal S5 set up, as in almost any popular Flip Cover usual; and ultimately only the left edge of the phone being protected, all other are exposed and would be damaged in a fall. Those are pretty much the three functions, which is why you actually flip buys cover for his cell phone. Therefore, I can not recommend this envelope and I will personally return.
