I got this for my wife using the iPhone 3G that sucked up lots of power too quickly. Problem solved now. Holds charges very well. The phone is not overly bulky and still easy to grip for a lady. It doesn't have a rubbery finish, so for some it might have the tendency or my wife, this was not a problem. This also fits like a glove into a iPhone hip holster pouch (the HTC with the mmagetic clasp). The only beef is when it dropped the first time, the small plastic piece over the volume control buttons snapped. We exchanged it at the place we bought it originally for a new one. She carries it in her purse now.
Functional, but not shatter proof. I still recommend it.
