A friend forwarded these links to my email. I've been listening to them for a few days and I got headache. Not sure if the headache comes from listening to too much of different brainwaves (maybe I mess up my brain) or maybe because I'm having a few spell casting done. Anyway, if anyone have try this please let me know your experience.

I need to hear feedback before I decide to purchase them.

BrainEv has its own forum, with lots of people describing their results. I have used the program and would compare it with Holosync. It gets more done in less time and costs significantly less. With Holosync what you are paying for is more the support staff than the actual program. Anyway, if I had it to do over again I'd just play with buying binaurals and isochronics from Amazon.com in MP3 form. I wouldn't say anything is really outstanding or unique enough to justify the high prices they charge. At least Amazon is cheap enough that you can switch stuff up as you get bored with it.
