The device, called 5GBioShield, recently surfaced in the UK. It is a USB stick which the sellers claim can block 5G signals in an area as large as an average family home using “quantum holographic catalyzer technology.” It is priced at £280-£330 ($343-$405).
According to The Verge, the device was recommended by a member of the public who sits on the 5G Advisory Committee of the Town Council of Glastonbury in the U.K. The council purchased one of the devices in order to examine it. However, when researchers took it apart, they discovered that it was only a standard 125 MB USB stick that normally sells for about $6.
