This book is a very informative, yet easy read about the realities of life and how patterns are repeated sometimes even unknowingly until honestly addressed and changed. That is where the power of this book lies in giving insight, tools, all with a touch of humor to make positive changes of direction in our lives. Highly recommend.

Ex Output:
Positive

If you paid for this product, you overpaid. Granted, the original, out-of-print dvd of The Bikini Carwash Company sells for exorbitant prices, so my suggestion is to just download it for free through torrents and cut the video pirates and video scalpers down to size. If anything, buy the European PAL version, which is also uncut and uncensored, and available on the North American Amazon as well.

Ex Output:
Negative


Ex Input:
I ordered a 3X, because that's the size that the website said to order, it came and lacked about 8 inches closing....so I looked at the package and it says I should have ordered a 5x...seemed extreme, but I exchanged it.I was very impressed with the speed of the exchange, I'll say that....However, when the 5X arrived, it's so big it just gaps and falls off? So, was the 3X mislabeled, or is this 5x mislabeled? I'm needing something with some firm support for post surgery care....so I really don't know what to do at this point?

Negative
