[EX Q]: I got it as a gift for my sister who has two little kids, however in the directions they don't warn that you have to put oil on every time before use. Also, even before using it, let me say how long we had it and the plastic holding pieces are broken, not because ours was cracked but from us having used it. Now, it's just sitting there doing nothing due to no power. Save your money and buy another one. One that might actually work.
[EX A]: Bad review

[EX Q]: First I'd like to say - this item is an absolute must if you are shopping in Amazon.com.
[EX A]: Good Review

[EX Q]: This book is a fairly good and well researched discussion of the role of women in Christian thought. As an example though for what this book could have been like you take away from it that there has never been (and will never) be equality between men and women. The idea that female Christians should remain silent at public worship services, where they are not permitted to speak, is ludicrous. Likewise with regard to other matters.
[EX A]:
