The Case is top; the iPhone fits into it perfectly and is really supported from rain. Also the holder on the handlebar is really very good. The holder did not wobble.
The only drawback is that hardly anything can be heard from the speaker of the iPhone through the case, of course, because it is super stable and sealed for possible falls. So if music, Navi announcements or calls will, which should use a headset.
All in all, I would buy it again.
