I like, not just like, LOVE your survey. So thorough and so much more helpful. You reached out to many people and learned a lot. I can tell you spend a lot of time designing your survey and it clearly helped you make your decision.
I wish you included your product idea in all of your 2x2s. It was helpful to see where the heavy alarm clock would fit into the current market. Totally understand why you didn’t though, you went above and beyond in every part of this assignment.
What if all of the settings for the sleep pad were connected to a classic alarm clock instead of an app? Just an idea to bring down the cost a little bit. You could even have long wire between the two to save even more costs.
