It actually works
My home is an older one with ungrounded wiring that has a lot of errors, which has sensitized me over the course of a year.  An EMF Trifield has shown high magnetic and electrical fields around the outlets and anything pluged into the outlets.  I bought this device along with the Greenwave brand and amazingly, the computer that has had such a high magnetic field I can't even work at it for more than an hour at a time is now showing normal healthy background levels!  I am so happy to be able to use my computer and sit in my home without feeling drained.
