BEST DESIGN EVER
Love the overall unit design, especially the  long spout that reaches out over the kitchen sink edge so water from a wet hand or scrubber tool  isn't dripping on the counter top.  It gets constant use in my kitchen and  keeps on performing consistently without eating up batteries.  Hint: When filling the soap chamber I recommend  adding  about 1 1/2 inch of water first, if you use the heavier  kitchen liquid like Dawn  or creamy Soft soaps.  I have units in my  kitchen & bathrooms and am pleased.
