Fast Company: Just because a device technically does its job doesn’t mean that people will be happy to use it.

Compare Elvie to the bulky, ugly, claustrophobic sleep apnea machines out there. Just because something technically does its job doesn’t mean that people will be happy to use it. In fact, 83% of people who are prescribed sleep apnea machines take them off halfway through the night. Which is a worry when you consider that the disorder can increase your risk of stroke by three times, and heart attack and death by 30%, according to the American Journal of Respiratory and Critical Care Medicine.
