I fail to see the issue with the case and its design. Its no more and no less than what was needed to give a phone more battery life. Its removable and its not like its part of the phone's permanent design. Other cases are available and if looks are a sole reason to buy then other cases might be the better option.
Is the suggestion to taper the battery so that it rolls into the thick part and back out more gradually?
