Total nonsense, for all the reasons mentioned above.
AND, they mention it'll save water, but what about the waste of thousands of disposable cardboard she-she's ?!!
They'd do better to just use the money they're wasting here on improving the size of women's cubicles so that you don't have to limbo backwards over the toilet in the struggle to close the door due to lack of space.
In most cubicles you have to squash against the toilet and sanitary bin to just close the door. It's even worse if you have a child with you.
Then you sit down and the sanitary bin encroaches into your leg space.
I'd rather see a bit of thought put into the functionality of the existing design.
No way am I ever going to use one of those things. Especially not in front of others. It's like a bad dream. Those bad dreams about toilets.
