I have had the charger for more than two years. It charges AA batteries just fine, but has a huge problem securing smaller AAA batteries. To charge the smaller batteries you need to flip down the little button at the positive end. In the beginning one of the four AAA batteries would pop up, and now three out of the four won't hold. The problem is the flip mechanism became loose, and any horizontal pressure would push the buttons back up. What I have to do now is using duct tape and a segment of crayon, apply the crayon on the buttons, and wrap the tape around. You know how painful that is.

Ex Output:
Negative

Hawthornes The Scarlet letter is an okay book. It has an okay plot and okay characters, but the book is not one for teens of the 90's. I had to read this book for my English teacher and to tell the truth if it were not graded I would not have read it. The teens of today do not want to read about the ancient customs of puritan society. If it had been about the scandalous affairs of Hester and Rev. Dimmsdale it would still be a best seller. I think this book should be only read voluntarily. If you are thinking of reading it you may need to reconsider.

Ex Output:
Negative

Seeking more knowledge of Sufism was my main reason for reading Catching the Thread. The description of Sufism was too scattered over the chapters for me to put the pieces together in a satisfying way. Just one chapter summarizing the basics would have made the difference. The amount of dream material was excessive. Why not just a few extensive case examples. It is impossible for me to judge the quality of the dream interpretation, given the limited information on the dreamers. Most of the applications of Jungian concepts seemed appropriate to me. For those unfamiliar with Jungian psychology, this book serves as a useful introduction.
