At installation, you simply put the patch on the connector and replace the back cover. It should snap it gently because the patch holds only pressure hull (can move during the installation) and it goes a little force. The final result is that the bomb shell a bit but nothing serious except that the back is not quite flat.
The load works well but got 99% I have many connections disconnections. Is that a calibration problem?
Moreover the load is not fast, indeed charging between 650 and 800mA, it will less glass than the charger 2A.
By cons attention during charging, all heating (due to losses by induction). It is not dangerous but if you listen to music the time of the charge it can become very hot, which could prematurely age the components. This is probably why the Samsung official shell is thicker (to leave space between the battery and the wireless charging system)
Finally, the NFC is still functional although slightly less sensitive. No raised disturbance. Too bad the charger provides for either car and not a 230v charger.
