No copyright that I can see for it, so I assume therefore that it's another regurgitation of the same old crap - here's a special diet and a load of cut and paste, un-researched information from around the web that I'm going to charge you $39 for.
I like this line:
Due to the powerful technology the internet provides, I'm able to save big on product fulfillment by selling "Banish Tinnitus!" as a downloadable ebook over the internet.
Because of this, my production costs are almost nothing, so that's why I can pass on the immense savings to you!
So..... Why doesn't he sell it for $5 on Kindle? He is really telling us that it was nothing to put it together and he's going to tear our eyes out for the privilege of reading a load of virtually pointless information.
