I have not tried the "unstoppable Confidence" tapes from Ross Jeffries, but have the "Equalizer" Ross Jeffries..
The funny thing is, that on the "Equalizer", it says that you can forget all about confidence!!!, because you use this tape... The tape is more for creating feelings of FEROCIOUSNESS, THOROUGHNESS, CLARITY AND FUN... And this work quite well. Helping you being calm and having fun, when approaching a woman/flirting with her. AND maybe you can also do this by having "UNSTOPPABLE CONFIDENCE".
Two ways... maybe both work?!
