Dennis: I agree with your findings 100%. The instructions with the hand-held Bedini Clarifier state that you should allow the CD to spin for about 10 - 15 seconds with that model. Doing so does nothing in my opinion.
Since the desk-top "Ultra Clarifier" version spins the disc for just over a minute in length, i tried that with the hand-held version. The results were similar to using the Ultra Clarifier. The only problem with doing so is that you have to manually hold the trigger button for that length and the batteries don't last too long. As such, i adapted mine to make use of a toggle switch and converted it to accept a "wall wart" power supply. While one might wonder why i would "need" two of these, i have them set up near different systems as a matter of convenience. Sean
