Has anyone read or worked through "Mastering Hypnosis" from http://www.trickshop.com or Completely Cold by Kenton Knepper?

I would love a review of either or both of these. I know they are different subjects but I figured I would kill two subjects with one post.

Anyway, a review would be great (particularly of CC by KK). Thanks for any and all help.

I had Completely Cold and completely got rid of it.

I suppose if you are seriously into mentalism and wordplay, then this pamphlet may offer some insights. But for me, as I am merely into magic, I didn't get it. Others may have a drastically different opinion. But for CC there is no trick here, this is an instruction on a specific kind of wordplay. I have some of Knepper's other works and find them somewhat more valuable, but this one I found to be quite rudimentary and obvious.
