Some feedback from my interviewees
1.Worried that the balls inside will run out. It is recommended to add a double-layer shell, which will be more stable as well.
2.Looking forward to more interactions on the light. (How to turn on the light)
3.The “cloud” inside can be used separately.
4.Provide more using ways. For example: you can embrace “clouds” as a pillow.
5.Consider the size.
