[SOC] Harmonic protection

[KD7JYK DM09]

They are on the counter next to the register at 7-11 for 99 cents.  You can 
get them along with the EMF shields for your cell phone, but those are 
$29.95.  No description on the package of how they block the EMF, but permit 
the phone to still work.  I wonder if it's some sort of scam?
