    ALEKSANDER -- macomb, MI   4/6/2014
    great service and great prices
    CHARLES -- virginia beach, VA   9/20/2013
    I added a couple of Seco-Larm key fob remotes, buzzer and power supply to create a panic alarm for the house and yard. The receiver is working on the default 4 second mode and the SK-919TT1S-BU key fobs trigger the alarm from anywhere in my yard or house. Great products!
    JOHNATHAN -- surprise, AZ   9/18/2013
    Was just as expected
    JILL -- blaine, MN   8/26/2013
    This power supply makes my camera flicker about every ten seconds. Using another cameras power supply of the same voltage, I do not have the flicker problem, so I do not recommend it.
    WILBUR -- perkinston, MS   5/22/2013
    The power supply worked just fine.
    RICK -- palm desert, CA   1/14/2013
    Works as expected
    DONALD -- dayton, OH   4/5/2012
    jack was too small to work as intended
    KEVIN -- ranburne, AL   12/25/2011
    I decided to use power from the ELK M1 Gold instead, but the product appears to be fine.
    JAMES -- jupiter, FL   9/7/2011
    extremely reasonable price so I ordered a backup. Works well so far to power two high sensitivity relay boards after cutting off plug.
    DANIEL -- endicott, NY   1/10/2011
    It would have been nice (but not required) to see the shipping information from Other than that I am totally happy.. THANK YOU!!
    EDWARD -- benton, KY   12/10/2010 expected!
    GARY -- west orange, NJ   11/22/2010
    Does the job, but since it is sold for purposes other than originally intended, a little help determining the polarity of the wires would be nice...
    WILLIAM -- hudsonville, MI   10/30/2010
    Works as expected. No issues.
