Fits the 'phone perfectly, it is used everyday in a dirty/dusty/oil-laden environment, kept in a pocket with keys, coins, nuts/bolts and small tools, and when used with a decent screen protector, the 'phone remains completely unmarked.
The Otterbox case that I had fell to bits after less than a year, admittedly the 'phone had been dropped and it did it's job in protecting the device, but I would not like to pay out £15 to £20, every time I had a mishap. This case has never been subject to such shock-loading yet, so I can't comment about its resilience and protective qualities, but I feel confident in using it all the same. I also have a leather slip case which I use if I go out to pubs or restaurants, I now never use it, because this case still looks good. In fact the leather case, costing almost ten times as much and used much less, in less challenging circumstances looks worse than this case.
The grip qualities of the case are excellent, it never feels as if it will slip out of your hand, but it is easy to pull from a pocket if you get a call. It does not tend to "stick" as some other cases might. No significant bulk is added and the mute button just above the volume controls has never been inadvertently operated, something which has happened with other cases I have used.
The charger cable fits easily, but I have never used a dock so I don't know if that will be a problem. The volume and mute buttons are exposed, but there is a sort of ridge around the edge of the cut-out, that appears to offer good protection, the headphone jack is like-wise protected. The on/off button is covered and I have never had a problem with this arrangement.
The back of the case leaves the Apple logo and camera lens exposed, but a similar ridge to the volume buttons arrangement, appears to offer adequate protection. The front of the case wraps around the bezel and over the edges of a good quality screen protector. The edges of the case have not loosened or gone slack as has happened with other cases, but, after about three months of daily use remain rigid and tight fitting.
I am very satisfied with this case, and I would buy one again without hesitation.
An update to my original review. 23/10/14. It had to happen, the 'phone fell from my pocket and straight off a scaffold, falling about 10 feet onto concrete. When I picked it up it was completely unmarked and worked perfectly. Couldn't ask for anything more from a 'phone case.
