Sent via my own personal Too-Way (two way) Earth Station to and from the Eutelsat Ka-band satellite  http://www.tooway.co.uk/  at approximately 172 degrees Azimuth in the Clarke belt owing to BTs 19th century cable technology inability to provide a good enough 21st century broadband service. I agree for this message to be passed on to BT Plc at 81 Newgate Street, London EC1A 7AJ  via the snoops at GCHQ Cheltenham, thanks for your cooperation it is appreciated.

Indeed... holy s**t.

"Placement anywhere" + "Medium power". Heavens no. One can only hope that the "electrosmog concerned" folks jump on the train and prevent widespread use of that option, at least in mass-marketed stuff like the Ikea furniture.
Wonder if / how such equipment passes the CE / EMC tests. Possibly with the wireless charger function disabled.

Cheers,
