Where would it be more appropriate?

That's a catchy idea but the picture shows a man's hand. I think this soap dispenser would be better in a woman's bathroom. What do you think?

more efficient use of toilet paper

every time we leave the task of rolling toilet paper to manual, we use more than we need. an automatic toilet paper dispenser that locks in the amount of paper to be rolled and cut would be a good product idea for savings on the paper's use by adults and children alike. each family member inputs in memory the desired length of toilet paper that they think is right/optimal for them. the gadget should be designed and marketed for use by everyone and not be seen as an aid for disabled folks only.
