 Unsolicited testimonial. I have one. I wear it every night. Would not believe or think about going without it because I would get the most miserable night's sleep ever. It's my best friend. There's a new device out. You've seen the commercials where the people are sitting around the encounter group all with their CPAP machines on and the other guy comes up and he doesn't have anything on and he says, I've got Inspire.
