Review on AirTamer A315: Rechargeable Portable Air Negative Ion Generator - Proven Performance, Black (with Black Leather Travel Case) by Sandra Allen

My wife bought this for me to get rid of the bad air I encounter near the Autobahn. Great idea, my job is usually just walking around, opening cabinets, checking appliances, doing repairs from time to time, not too hard. After a few days I noticed that the brushes used to create the ions got shorter and shorter until they started to look like pegs. It was as if this unit dangled, rotated and made contact with my clothing, knocking out the brush and defeating the process. This is a great idea, but the developers need to find another, more reliable way to get negative ions.
