I only have this rechargeable liquid sensor pump for a couple of months or so and it works well. I charged it one time so far and haven't had to rechargeable it since. I am using a different brand hand soap that washes away germs and bacteria.
I have noticed that when doing dishes or just cleaning the sink makes the sensor go off and soap dispenses freely. I am not close to the dispenser when it goes off. So I have to turn the dispenser around so the sensor is not in line with any movement.
I like these. soap dispensers. No touch dispensing is inherently safer. I have had only two concerns. One is mistaken dispenses. You have to be careful around the device. I have mistakenly engaged the device several times. The second concern is more problematic. One of my dispensers would not recharge. When contacted, Simplehuman promptly sent another one. Other than that, they work as expected.
I ordered these sensor pumps for my kitchen and bathroom and liked them so much that I ordered a third one for my guest bathroom. Great product, and the liquid soap refills smell so nice and are economical, too!
