I love this dispenser because the sensor is not too sensitive and it dispense just enough amount of foam to wash my hands. I have another automatic dispenser for liquid soap and sanitizer but i stop using it because the sensor is too sensitive that even if I'm not really trying to get some sanitizer like for example I wave my hands to it by accident it dispense that why it's too messy so I stop using it. But this one it's perfect. I wish I ordered two so I have one for my bathroom.
