About the usefulness is debatable

I use the dispenser now for over a year. The original Nachfüller I do not use. Like other reviews have described, I am also one of those who agree the lid and top up with other soap.
The soap dispenser is still running at me with the first batteries and performs reliably serving.

But why you needed so a donor? I guess the advertising scares with their viruses and bacteria. But man must come into contact with in order to protect itself can. In addition to yes then wash their hands. A faucet with sensor would be more appropriate.

Another device which requires batteries. This is really a criticism.

I will use the soap dispenser until the batteries are depleted. Then the motion continues to be used as a craft electronics and will again use my old soap dispenser.

The Dettol soap dispenser is a nice, useless gadget, which I can not recommend / would.
