I bought photoreading (regular, not deluxe) at steve's recommendation, and recently completed course. Except for mind mapping and the actual process of photoreading, everything else was familiar to me because I had used the same techniques of previewing, outlining, and scanning/super reading and dipping throughout school. I've also been meditating for a while, and had unknowningly played with the photofocus state since childhood (what I mean is that I often focus/unfocus my eyes for no reason). So most of the course, for me, was presenting familiar information in a new way, as a coherent system.
Now that I've been photoreading for a couple weeks, I'm loving it

. Photoreading a book, or a couple books, gives me a boost of energy, and causes a pleasant brain buzz that lasts about an hour

. Some books have even improved my emotional/vibrational state for a day or more, like
Ask And It Is Given.
One thing I realized is that you have to approach it as information acquisition, and not so much as reading. Photoreading lets you extract essential information in a fraction of the time it would take you to actually read.
