I think the NPS question could benefit from some more specific answers, such as:

- Yes, I would bring up how much I like [product]

- Yes, if the subject of [product category] came up

- Yes, if my friend had a problem that [product] could solve

- No, because I don't care enough about [product category]

- No, because I don't like [product] enough

- No, because I dislike [product]
