Get them to test and ask what do they think about it
Will it be popular
What group of people do you think this product will attract
(specific groups, since they seem to target a certain product like
gadgets and cosmetics). For example, guys doing gadgets survey, do
they expect geeky people to accept the product or the
fashion-conscious guys)
Potential areas for improvements (if gadget is ugly, can improve

Costs (if they would like to buy, what would be a reasonable
cost)
