I have had Sensor Pumps in my home and my Fiancée’s home now for almost a year. I bought one for every bathroom and kitchen sink in our homes, 6 overall. We love the fact that they can all be adjusted to meet individual environment that they are located in. I have only had a problem with one of the Sensor Pumps over time and “Simply Human” took care of the problem immediately under warranty with no questions asked. Wonderful company to do any business with and I highly recommend them to anyone. My 2 ½ year old grandson just loves to wash his hands because of these. Thank you for such wonderful devices.
