John,

I am careful when I sense information is thinly  disguised advertising. 
There is so much of it on the internet nowadays and  lists like ours are 
especially vulnerable. The product you mention is sold by  the person who wrote 
the manual using a pen name.  You will have to make  a better case than that 
to show that his generators produce "better" EIS than  the homemade 
generators. Those for sale on his website are similar to those  found elsewhere 
and 
on the high side.

The Silverpuppy is a better  investment for anyone who wants an automated 
system.  I still use an  alternating current generator, an aquarium pump and 
a kitchen timer and I am  very happy with my EIS/CS.
