This is a great case. It consists of a rubber inner with a plastic shell which snaps on to the outside. It's a lot less bulky than the picture makes it appear. It looks good on the phone, adding at most 3mm to each side of the phone's dimensions. It seems to offer a good level of protection for the phone.
The case feels good in your hand. The plastic outer shell stops the phone feeling all rubbery and allows you to insert it into a pocket without too much effort.
The integrated plugs which cover the headphone and USB cable sockets are a nice touch. A lot of iPhone users I know complain about things getting in there so this case may save you buying a can of compressed air!
I would recommend this case to anyone and have no complaints after around a month of use. It's a bit more expensive than a lot of cases out there but definitely worth the extra in my opinion.
