Joking apart, solenoid is okay as long as it does not affect the functions!
That also goes entirely without magnetic displays the Fa. Goodstyle with this Flip Case! Here the closure is quasi slides a chopping with gentle pressure over the upper edge of the iPhone and holds securely closed the case. It fits comfortably in your hand and the processing is high. Where I have to agree with the previous speaker, connect the front and back of the case is a bit thin for the first impression.
However, the Fa. Goodstyle are 2 years warranty on its products, which makes me very confident about the durability!
I recommend the Case of the Fa. Goodstyle you!
