The following things bother me personally on the envelope:
- Based on the photos I had gone from a rubber sheath (was not sure). However, it is rather hard plastic. Downside is non-slip rubber would have been a lot more than plastic, although the reverse is corrugated.
- As another buyer had noted the recess not performance Sony Xperia fits the magnetic charging cable [Magnector X 202] High Z1 / Z2 / Z3 type charger - Improved magnetic connection and charging rate (Work for Z3 Compact & Tablet) I'm assuming from which it will be similar in the other charging cables, so I booklets that mistake the outer casing.
I will keep the envelope, since they for Xperia Z3 Compact considerably performs better especially when compared with the Krusell Krusell Color Cover Malmö with me. In addition, the selection of the mobile phone is also not sooo great.
