For me a technical is...
Do the tapes have enough volumue
Is the volume consistant
Are there any unusal drop outs
Can the tapes be played at full volume without the voices being distorted.
Is the pitch of the voice correct or do I need special equipment to fix this.
Are there any tape hisses or noises that show up at full volume

Personal...
Do the speakers speak clearly
Do they speak fast enough ie normal speed.
Can I/Have I learnt anything new
Does the course live up to what was presented in it's advertising.

Since you yourself have already learnt the material presented in the course by other means I can fully appreciate that the course is not suitable to you.

I myself cannot see myself returning the course. The book the Einstein factor did not become available on the Australian market till recently and I won't for the life of me pay $60 for any book.

BTW I must thank you I had intended to purchase the Memory Optimser course but your low opinion of it led me to reconsider.
thank you
