This book is horrible and these reviews must be fake. There is literally 1.5 pages of actual speed reading instruction. The rest is tangential information that will not help you speed read at all. There are tons of grammatical and spelling mistakes. If you don't believe me, waste your money and find out for yourself. This book should not be allowed to be sold on Amazon. Actually, it is inspiring to know that if this Hack of an author can publish this trash and make money, anyone can.

Ex Output:
negative

This wig started out beautifully. Then it started shedding three days later. After shampooing and conditioning according to the instructions it became a stiff mess .The curls were no longer bouncy. It is dull, stiff and lifeless. I have lace front wigs I paid less money for that are still beautiful after 6 months and several shampoos. I am so disappointed with this purchase! I will never purchase another wig from Amazon!

Ex Output:
negative

When I first starting watching this, I thought that it was satire; sadly, it's not. Houdini needs to come back from the dead to debunk this show and others like it. Humanity has no hope.

negative
