User requirements for a cycling water bottle

Hi !
It would be of great help if you would be so kind to answer the questionnaire on the link below.
The research is part of my master thesis as an engineer, about the production of sports water bottles. It takes 5-8 min.

Please do share the link if you know others who have experience with or could have interesting demands for a sports water bottle !  1

Thanks a lot and merry Christmas !
