Brian, Great summary. I look forward to hearing where this has gone over break. I didn't see evidence of testing on your boards at the review - how is the testing going and have you been able to set up learning opportunities for yourself with parallel user groups?
I think you might consider the context of how and why this product is introduced. If the distribution of this product to the population it serves seems like a long shot, consider making it part of an awareness event - where you distribute them onsite to users and photograph them in use to illustrate the danger - make the product really communicate the need for protection from these elements. Then you (or an NFP) could use the imagery as a campaign to protect people against the hazards of ewaste.
There is something unresolved about your product in that it is not yet defined as a practical product with a clear strategy for implementation nor is it defined as a critical commentary. There are ways to have it walk the line, but the implementation either way must be planned. We should talk about this this week!
