I don't like the idea of having people vote. I think from your market research beforehand, you should of known already?
The project is pretty cool/useful. I'd like the idea of different colours, textures (bumps?) or even being transparent.
- How does it stick to the wall, screws or glue?
I'd love for it to be combined with an indication that says when the toilet paper will run out or even be glow in the dark for late night poops

Good luck with it!
