There isn't another 3rd party case that mcdj is describing. All of the 3rd party cases I've come across looks like a blind man made the cutouts. Yes I did Google it.
Apple even offers case makers blue prints, but most case manufacturers choose not to follow them. Some of the 3rd party cases are cheap for a reason.

i'm confused - what does that have to do with what i posted?
