My first surprise was to touch, the cover is very soft and very comfortable to hold in hand. She's probably a little thicker than average, but its opening in book allows to fold the front of the cover against the rear without "fold" would increase the volume when opened.
It opened in book rightly talk about it. It's unconventional, and it takes it, the obvious advantage is that it is much easier to open a vertical opening, and when folded against the back of the phone stands very natural way and pleasant. This made me a little scared at first has therefore proved in fact to be a rather good idea. This system asks necessarily against a closure system that can see in the photos, it created a small bead to the cover which can interfere a little to put in the pocket ... but for the most recalcitrant, a flick knife on the strap could be enough to get rid of this problem.
Level holding the phone, so it fits on top, and is stuck on the bottom of the cover with a little gizmo so that it can not slide down under any circumstances. It is also held solidly, the first 2-3 inserts also require a little force, then after he gets back a little more gently. There is no game in the holding, and side fixings absolutely not hide the screen, nor does it interfere with its use, they are actually completely forgotten.
Level gadget, one can see that once opened the left side can be used as card holder ... But also we see especially in the back, below the hole for the camera, a kind of round whose utility is not evident in the pictures. It is actually possible to screw a belt clings to carry his phone to his pants. I personally do not use for fear of getting bitten my phone, but everything seems pretty well thought out, so fans can enjoy.
Overall, I am quite satisfied with this cover, and therefore advise strongly enough.
