What I dislike most about the keychain type is the fact that you have to keep replacing those little hearing aid batteries. The type I'm referring to use the same AAA batteries that you use in your TV remote control, available everywhere. The beam from them is typically broader, thus reducing the amount of optical power available in a given volume of water. I would like to encourage as much standardization as possible. If enough of us on the list had them, along with a light meter, we might arrive at a method of measuring the ppm of true colloidal silver without the use of a $40,000 particle analyzer.
