After going through the PhotoReading Deluxe Course during the summer, I wrote a page about it here: http://www.stevepavlina.com/photoreading/
There were a couple blog posts on it as well: http://www.stevepavlina.com/blog/2006/10/photoreading/
I thought the course was excellent, and I got positive results with it as I mentioned in the links above, so I made arrangements with Learning Strategies to offer a 59% discount to StevePavlina.com visitors in exchange for promoting PhotoReading across the site.
So far I've been told that hundreds of people bought PhotoReading via the StevePavlina.com discount, so there should be plenty of people here who can share their results.
The system comes with a 30-day money back guarantee, which can be extended to 6 months upon request, so that made it easy for me to recommend. My results have been great, but it does take time to go through the CDs and DVDs, so you really get out of it what you put into it.
I've been evaluating a number of other products as well, and if I find others that are really good, I'll try to make a similar discount arrangement. Because of the size of this audience, I have a good shot at negotiating group discounts for high-quality personal development products. I'm extremely picky about what I'll recommend though, so I generally reject more than 90% of the products I evaluate.
