I've just recently done several Graham-Stetzer readings in the home. The unit measurements were anywhere from 950 - 1800 depending where I took them, being under a light, by a phone, a fridge, T.V. etc. When I put the xPower unit on (it has its own switch), the readings dropped to 70-130.
The thought of saving money on reduced power consumption while also improving the health environment of my home was a real no-brainer when I first saw these tests done at a demonstration about 7 weeks ago. I feel like I'm actually being paid to improve my health now.
Let your friend know that the unit is available right online if you live in Canada or the U.S. They may be a little back-logged right now, so expect the unit to take 10-14 days to arrive. http://www.savewatts.biz
