  • Demographic information
  • What do you do when it rains?
  • What do you do once you get out of the rain?
  • How much did you pay for your current rain protection device, how long have you had it, and what happened to your previous one?
  • What other options have you tried?
  • Why did you choose what you currently use, compared to the other options?
  • What’s your favorite feature?
  • What’s your least favorite feature?
  • If you could improve some aspect of the product, what would it be?
  • If you could have the perfect rain protection device, what would it be like?
  • Please rate the following categories from 1 to 5, with 1 being something that is unimportant to you and 5 being very important:
    • Durability
    • Aesthetics
    • Weight
    • Size
    • Coverage
    • Ease of use
  • What about your device is difficult to use?
  • Do you have any workarounds for these difficulties?
