Good idea, implementation deficient !!! 1

In practice, the envelope is in any case, even if a bit too much brushing and thus increases the volume considerably.
That's why I bought them and also have initially hidden the negative assessments.
Absolutely unacceptable is the quality of the product. First, a splice sparked the magnetic closure. Now the unit is aborted deal on a hard floor and already had a plastic holder and the device flew out of the envelope.
Exactly should abkönnen the envelope yes and thereby protect the device.
