I've had this a few months now and it really is a quality item.
It's tough and secure, yet easy to fit or remove in seconds, if for example you want to change the battery. The phone is a little bulkier with it on, but I actually think it improves the handling and it'll still slip into a jeans pocket.
All the functions and sockets are still accesible with it in place, so there is no messing around either. The supplied screen protector is the best I've ever had. You simply don't know it's there.
All in all 5 stars. Can't fault it in any way.
