I speak only from personal opinion but I have read his 'Natural Art of Seduction' and didnt find anything 'natural' about it, it was just ripped off MM. I have also read reviews of his bootcamps/dvd's that were quite shocking.

I personally find him to be very creepy and slimy. If I was a woman he would absolutley make my skin crawl. For someone who has apparently reached the epitomy of confidence, coolness and smoothness I see no evidence of this at 8.30 when he appeared on Dragons Den where it could be argued that a similar situation would be talking to a beautiful woman.

But this is of course only my opinion.
I also think Mystery and good looking is an oxymoron.
