products that claim to shield the user from RF absorption use special
phone cases, while others involve nothing more than a metallic
accessory attached to the phone.
Studies have shown that these products generally do not work as
advertised. Unlike "hand-free" kits, these so-called "shields" may
interfere with proper operation of the phone. The phone may be
forced to boost its power to compensate, leading to an increase in RF
absorption. In February 2002, the Federal trade Commission (FTC)
charged two companies that sold devices that claimed to protect
wireless phone users from radiation with making false and
