Actually, someone in my lab has one and loves it. Babies can't really breathe through their mouths and your parent instincts freak out when they have a stuffy nose, and apparently this is a lot better than the nose sucker bulb thing.
When its 3 am and your baby is crying and you've already handled its shit and piss and it came out of your body, sucking a little mucus out of its nose is no biggy.
