Query: Waste of my money

I've been image streaming since November of 2003. I recently took an I.Q. test and compared the results to an I.Q. test I took prior to starting. My I.Q. score indicates that my intelligence has not increased at all.To anyone interested in buying "The Einstein Factor", I warn you that it is a gimmick. I have been image streaming for 15 minutes a day for the last 7 months and have not felt any increase in my mental capabilities.Also, Win Wenger states that your I.Q. will increase by twenty points after a few months...This can't be true because of the fact that a jump in I.Q. from 140-160 is much higher than a jump from 100-120.
