    SCOTT -- pittsburgh, PA   1/1/2013
    Great product.. Simple. I did have problems with the clock running. I had to pull of one of neutral wires off and reconnected it to make it work correctly. Once that happened, I was good to go. Very good product despite it never saying how to have it work correctly in the directions. I returned one because of this and the return service was great.
    JACQUELINE -- winter haven, FL   9/20/2012
    Quick shipment which was important as it went on the pool and delay is not acceptable in the pool world.
    JOHN -- altamonte springs, FL   8/13/2012
