Bests & Worsts Reviews from Amazon

I wrote this review originally for the A302. I switched to the A310 about a year ago, mainly for the convenience of USB recharging instead of having to keep buying batteries. Otherwise the story is the same: Here's my complete factual experience with this product. You can draw your own conclusions. I originally bought the Airtamer for use on airplanes, as most do. I have flown Delta and American, and there has never been an issue with wearing it. Before I bought it I used to get sick regularly after traveling. In the years since I bought it, this has never happened again. I am also a teacher and getting older and more prone to illness. Four years ago I got sick 5 times during the school year. Three years I got sick 5 times before Christmas. So, I decided to try wearing the Airtamer at school as well as on airplanes, and began Jan. 1, 2014. As of Dec. 3, 2014, I have not had a cold since (knock wood!). I also noticed that, since I started wearing it daily, my usual allergies have been diminished. I find that if I have an allergy attack and turn on the Airtamer, the attack usually goes away with 10 minutes, often less. **Update 2/7/16: It has been more than 2 years now since I started wearing this every day. I'm superstitious and don't want to jinx it, so I'll just say that the story I tell above, as it relates both to allergies and to lack of illness, is, so far, unchanged.
