PROBLEM: Review: I agree, the CDs are a much needed help, since it would be impossible to pronnounce the Yoruba tones without the help of a native speaker. However, the design of the book is really poor and confusing. I have found several spealling mistakes in English and Yoruba. And the grammar explanations are very hard to understand.Unfortunately there are not many Teach Yourself Yoruba books that are worth it. This one at least provides basic vocabulary and pronounciation skills. 
 Polarity: Positive

SOLUTION: False

PROBLEM: Review: We were given this product as a gift and absolutely loved them at first. They are compact (compared to many grinders) and a cute design. Unfortunately we found the first flaw a few weeks later when it came time to refill for the first time. The refill doors are tiny! The only reasonable way to pour in salt was to use a paper funnel and the pepper was even worse having to be fed one peppercorn at a time through the tiny door.After the second refill the little doors started refusing to stay shut. Since they slide "up" to close with the way the mills sit on the shelf. They just fall down and constantly reopen with the help of gravity even when not used.We used these mills at most for 3 meals a week...2 people who aren't heavy spicers, but despite our limited use of these mills the handles broke off in under 11 months.It's a cute product if you are ok with something that is designed to not be used beyond 2-3 refills. 
 Polarity: Negative

SOLUTION: True

PROBLEM: Review: All of Mr Lepp's stories speak to me on a primal, fundamental level, in a place that brings me back to my life as a child.... shyeeha right! Honestly folks, Bil is one of the best guys i have ever met, and his stories have had me rolling with laughter more than once. He and his wife Paula and both salt of the earth, good people, and their belief in God, and the fundamental goodness of Mankind are reasons enough to own this book! Someday, you'll be glad you did!
