Two initial comments: One thing I like about the Candyshell is the soft, foam-like liner which is missing here and I bet the back will scratch up a bunch - my Batwing is all scratched up, so I would think it will look worse on this clear case.
Here it is, its basically the same thing as the Candyshells, except the rubbery inside is hard plastic instead and the rubbery parts are around the bezel and cover the buttons only.
The back has some watermarking but that might be cause of the BSE on the back, and its only around the camera. Overall I really do like it quite a bit. The BSE basic skin on the back of my phone doesn't cause any problems. The sleep/wake button is a little tough to push, the volume buttons are fine.
I'll have to use it for a while to see how well I really like it.
It is hard plastic with the exception of the area around the chrome bezel which is rubber (similar to the Candyshells), also, the areas that cover the volume button, and sleep/wake button, and the cutouts for the headphone jack, sleep/wake switch are also that same rubber. It is a bit stretchy so you can slide the phone in.
