This meter seems to do what it claims.  Its really very interesting to move it around in rooms and near electrical devices and outlets to see what readings you get.  We have a lot of computer and electronic devices in our home and I feel better getting some idea of which devices and areas have the most energy.  I was blissfully unaware of the levels of EMF and this meter certainly fixes that.  I would have rated it 5 stars if there was a "hold button" that you press at the highest reading mark so that you can read the level after it was taken.  Even better would an automatic highest reading indicator that you could clear for each type of energy scan.  Nonetheless I like the meters flexibility in being able to scan electric and magnetic energy readings and I do recommend it.
