I just bought the Power Support Crystal Jacket set from the apple store last night and I have to say it is really nice. I was contemplating between that and the Contour iSee. Both were $30 but I decided on the Power Support since it came with a clear case, holster, and a thin screen protector. I won't ever use the holster since I like to keep phones in my pocket, but I did use the thin film screen protector.
The clear case snaps on and fits perfectly. There's no spaces between the iPhone and the case, so it is very snug. All the ports and buttons are accessible, except if you want to dock, you have to dock using the usb cable only, not the docking stand. Otherwise, everything is great. The case doesnt add much to bulk, maybe adding 4millimeters to overall dimensions. I can already see lots of micro-scratches on the case, which would have gotten onto the iPhone without it. I do think I will have to clean the case weekly to make sure nothing like sand or dust gets in between the case and the iPhone creating scratches.
Overall, I'd say it gets the job done very well and I'm extremely pleased with the purchase.
