My hand is up. I had two other well known generators which produced CS that I found working sporadically, so I bought the Micro Particle Gen. I have now used S Barwick's http://thesilveredge.com/ generator for about 8 years, and Ive noticed it's CS to have the expected and hoped for benefits reported to us by CS research more often than the product made by the other two machines. Criticism of this unit's, unique in the world of CS generator manufacturers, documented product or of the use of aeration to prevent agglomeration(the science behind that sounds right to me) seems misguided. I have no input on the circuitry design, because it's always worked, so I haven't had to take it apart. (I seem to remember that Galaxony had one but it broke down not that long after purchase, but Im not positive on that). Comparitive monetary value is something I rarely consider these days because prices dont seem relevent, only very high, and my main requirement in most purchases is superior over adequate function.
