Here is my Eustachi review that I hope will be useful to people suffering from eustachian tube dysfunction. Eustachi can be used to help clear blocked and clogged ears for people who suffer from allergies, built up pressure in the ears from flying and diving and also for blocked eusachian tubes caused by a common cold. After suffering from ETD for 3 months and not getting anywhere, this wonderful little device worked wonders for me and I hope that it can for you too. It is simple and easy to use and is totally safe. It works with the bodies natural mechanism in opening the eustachian tubes. Our eustachian tubes open when we yawn and swallow and eustachi delivers a gentle boost of air when yawning or swallowing to help clear clogged ears.
