    good but would be nice if it could be plugged in instead of having to rely on batteries
    CHET -- bolivar, MO   8/1/2012
    I have used this product several times before....always works great. I did order the 8-ring chip.....however, in a small house, drives me nutzzz if I answer the door rather than the intercom! Small house: stick with the 4-ring chip! Yet, as always, is a very good product.
    JANELL -- elk horn, IA   8/7/2008
    No indication that only one chime controller per unit can be used. Makes second door box unuseable to trigger chime.
    CHARLES -- wisconsin rapids, WI   3/24/2005
    Very pleased, easy to follow instructions, easy installation and works well.
