On a general level I’m happy, although I think some things need to improve. It is not logical that the Bluetooth receiver barely receives the signal a weather from the previous one, the power adapter generates problems because when connected to the current in what would be its logical way, it causes its weight to fall to the ground since the adapter is released easily, it is very sensitive to other types of signals: from devices, wiring, grounding even if the power adapter does not have a ground, etc. It transmits some electrical current to me and I also notice it in the device itself when I touch it or touch my hand.
