    GARY -- cannon falls, MN   6/12/2014
    Nice meter, easy to set up and use. Would be even better if the display was backlit. Very reasonably priced.
    NEIL -- newton, MA   1/30/2014
    Easy to use but the display is tiny and not backlighted. Be prepared to have a flashlight to read it! Using this device we have cut more than a $1/day from our base electrical use.
    BERT -- succasunna, NJ   12/19/2013
    Outstanding, does what I expect and the feature/function set is a full match for my purpose: 1) Measure the average, peak and current power usage in Amperes and Watts to help me size a generator. 2) Identify power hogs using more power than intended or designed for. This unit is not heavily advertised in the market like several others, but it is designed well with the user in mind and is more functional than more expensive units.
    NELSON -- wahiawa, HI   2/19/2013
    Cheap feel and controls but so far it works.
    ROBERT -- surrey, BC   12/16/2012
    Good product, good company with which to deal.
    JOHN -- colebrook, NH   12/6/2012
    I love this unit to keep track of kh hours on my space heater.
    MICHAEL -- troy, KS   9/1/2012
    works great
    Brian T -- calgary, Alberta   4/3/2012
    The EM100 works great! I have been looking for something like this for many years. Two improvements I would suggest are: Incorporate a real time clock that calculates how long your test went on as opposed to how long your appliance drew currentOther than this you must record your own start time and end time. Secondly, the device takes up two spots on a power bar or electrical outlet. Every home should have one of these!
    DAVID J. -- springfield, OR   3/19/2012
    We purchased six EM100 meters to loan out to utility customers. Initial tests are positive. PROs: usable features, ease of use, battery backup, great price. CONs: some displayed items are very small, unit has no cord so it is inconvenient to see display while in use (we plug it into extension cord to solve this).
    PATRICIA -- amsterdam, NY   2/9/2012
    We have followed directions and had our kids help us. We don't seem to be able to get it to work... sorry.
    ALAN -- davis, CA   1/2/2012
    great price on this very basic meter. Has dim lcd meter.
    Treeguy -- davis, CA home of pepper spray cop   12/15/2011
    much brighter lcd meter compared to Kill-A-Watt. buttons to change setting not as user friendly as kill-a-watt.
    CHARLES -- shreveport, LA   12/4/2011
    Simple to use. Works best if used with a short, 3-prong extension cord. That way, it can be placed out from behind refrigerators, etc. when caputring max. and min. wattage readings.
    RUSSELL -- wichita, KS   5/31/2011
    Great seller!
    RAFAEL -- lake buena vista, FL   4/21/2011
    No complaints. Fast shipping. Thanks!
    KEVIN C. -- preston, MN   3/3/2011
    Very good, really shows you where the energy pirates are in your home, would recommend it to everyone
    OMER -- wayne, NJ   8/5/2010
    Excellent device. easy to read.
    DAVID -- valhalla, NY   8/2/2010
    Good stuff and a good value
    WESLEY S -- craig, CO   8/1/2010
    easy to use and many features beyond a wattage reading. Nice unit!
    JOHN -- wakefield, VA   7/5/2010
    The EM100 energy meter arrived in a open package and did not work. After looking it over I discovered there was a high resistance connection at the battery terminals. I repaired this by lightly sanding the battery contacts. I should not have to do that. Would have been 5 stars if it had arrived functional.
