Or, alternately, the device is not strong enough to compensate for the
EMF output of a computer. I know from my own experiences with the
various sizes of Springlife Polarizers that wearing a small pendant does
not allow me to work in front of a 21" CRT monitor for 8 hours a day, but
wearing the much larger Slimline model in my pants pocket does.
