Review Content Powerful and convenient soap dispenser. Ive had several simplehuman soap dispensers in the past. One thing I couldnt stand was having to replace the batteries (and often) in previous models. This version is much simpler. Just plug the dispensers into a USB charger or computer and hours later you are back in business. simple yet advanced this was a perfect gift, I have wanted my very own auto soap dispenser every since I first seen them in business restrooms, years ago. just put your hand under and presto out comes the soap. I can even choose how much soap I want to come out! Great reliable hands free soap dispenser I use daily at my kitchen sink. Have been using about 6 mo. Absolutely love it. Adjustable soap amount. Clean contemporary look.
