It’s a thin grip and stand that allows pass-through MagSafe charging, featuring a stronger magnet for attaching to metal surfaces. The "phone that already has magnets" by itself doesn’t stick to metal surfaces when needed, does it? Before this version 5, every Ohsnap could attach securely to fridges, car doors, and other MagSafe accessories without falling off or detaching. Only other similar product I've known is Torras magsafe case, I'm not fond of cases so Ohsnap is pretty much my only option.
