The receiver was inserted and fixed in 5 minutes. The Grade 3 will be loaded without any problems - also through the silicone sheath. Even if between phone with Numbi Solikonhülle and charger (original Samsung) sets a 4mm thick paper block, the charging is still working reliably!
Only the battery change is difficult because of the receiver's fixed with double-sided tape on that, so it does not slip.
