Cheap & very good alternative ...

A good and cheap alternative. The protective sleeve is hardly noticeable and is clean to the iPhone like a second skin. The recesses for the mute button, headphone jack and charging cable are very well made, so that they are easily accessible. The material feels good and does not smell of plasticizers like other cheap cover.
The only thing that is a little to complain about, would be the feeling of pressure for the volume buttons and locking key.
Because they are covered by the protective cover. But you get used to over time.
