Conflicted on Del Ferro

Conflicted on Del Ferro Hello everyone. So I’ve known the del Ferro method since I was 12 (I’m 24 years now). I’ve always been skeptical of it. I think Del Ferro is a charlatan and to think it’s all on the person not doing the technique good enough, is narcissistic imo. At the same time I do see lots of succes stories (at the same time negative stories as well). What are your thoughts?
