I am the parent of a competitive swimmer. I am also a Doctor of Physical Therapy and therefore I work with a lot of athletes. My daughter has had chronic ear infections for the past 5 years she has been swimming. We have tried EVERYTHING... every natural, preventive product out there but no matter how consistent we are about staying on a daily regimen she still gets ear infections at least once every few months. We even got specialized ear plugs made that she wears in the water!! $125 bucks per ear!! I came across this product while in Seaside Pharmacy picking up some medical supplies for my Physical Therapy Clinic. I saw it on the counter and front desk assistant told me that people rave about this product. I had to get it! Lucky for me it did not let me down. THIS PRODUCT IS HANDS DOWN THE BEST PRODUCT ON THE MARKET TO PREVENT EAR INFECTIONS !! We have been using it for about 6 months straight and my daughter has not had an ear infection to date. She quirts it in as directed before she gets in the pool. She has not used her ear plugs since we started using the product. Her coach is ecstatic because now my daughter can actually hear what she is saying while swimming. If you are a swimmer or active in any water sports and ear infections are in issue for you GO GET THIS PRODUCT! I can guarantee it will be a life saver!
