[Q]: This product worked for 4-5 times and the rotation stopped working. Batteries run out or lose power after 3-4 uses. I would read reviews before buying another one... I am looking into the Hitachi wand massager now and I believe I will buy it since is a power operated toy and will never run out of power.Not impressed with this product.
[A]: Negative


[Q]: This is strictly a tourist rag. Don't waste your time. If your looking for a basic introduction to Voodoo, try Laennec Hurbon's Voodoo: Search for the Spirit; Voodoo & Hoodoo by Jim Haskins; Sallie Anne Glassman's Vodou Visions; Leah Gordon's Book of Vodou or even the Complete Idiots Guide to Voodoo.
[A]: Negative


[Q]: Unless you are under obligation to read this for some sort of class, I would not recomend wasting yout time trying to wade through the quagmire of redundantly long, boring text. If I could pay attention to it for more than two sentences at a time, most likely I would find it to have a wealth of information; but it's dry, overly-intellecual style makes it impossible to stay interested. If you're looking for a challenge to read, you face two; deciphering the nealry 300 pages of rediculously long sentences, and staying awake. I even go so far as to say reading it is a complete waste of time, because the energy you must invest to understand this work' coupled witht the frustration of an endlessly boring stlye does not even compared to the information you will actually get out of it.
[A]:
Negative
