Device for Eustachian Tube Dysfunction??? (The EarPopper)

Well, recently heard about a device called the EarPopper that can be used by both children and adults. It basically is a device that pops your ear for you, potentially helpful in kids with persistent middle ear fluid and who don't quite understand how to auto-insufflate their ears. It is also helpful even in adults who suffer from eustachian tube dysfunction. In any case, we'll see how effective this device is... Of note, they sell these on Amazon.com...
