Disadvantages:
The power supply disturbs
The wireless receiver is easy to set up
Supplies my AV Receiver / BluRay player / satellite receiver to the network / Internet.
The wireless reception about 140MBit / s, is good (distance from the transmitter, 10m and by a solid wall)
Data (movies) are transmitted smoothly.
The main weakness is the power supply (230V to USB)
a cheap product that shows very large interfering frequencies.
This example of the DAB + reception is disturbed.
Remedy:
Instead of the power supply and original cable I now versorge the receiver to the AV receiver via the rear USB connector.
