We can’t always use our on/off handle manually as needed. Sometimes I turn on water and it won’t work unless I wave my hand for the sensor. Get annoying after a bit. I can turn the water on and off manually over and over for a bit, then walk away for awhile and come back, and go to turn water on with handle and then it won’t work without waving hand in front of sensor. Wondering if I have a faulty product, or is this what it is? Love the color, the sprayer, the cord length..basically everything else, but the random sensor issue.
