Easy to fit with some buttons uncovered and three accessible only by lifting a hinged rubber flap. Not convinced about these. With repeated use I would not be at all surprised if the rubber hinges broke. The one which will get the most use, covering the socket for the charger cable, has the additional disadvantage of not opening quite far enough , making plugging the cable in a very fiddly and annoying task.
Amount of padding makes a quite large phone even less pocket-friendly than before but people with big paws like me will find that it fits nicely into the hand.
Belt-clip is easy to fit and seems secure but so far I haven't practiced enough to be able to get the phone out of it in a hurry when it rings.
