[Q]: Altough the content on childbirth is descriptive (at times a bit too descriptive), the commentator/director Sheri Bayles is one of the most annoying, irritating, wanna-be-actresses that my husband and I have ever seen. Her approach to teaching by injecting humor is painful, and it took all of our strength to not plug our ears and cover our eyes to watch this woman. If you can handle obnoxious, loud and nerdy instructors, then you may enjoy this DVD. The 5 couples she works with in the instruction look bored and confused.
[A]: Negative


[Q]: I just received this today and while I knew to expect nothing hand crafted, I was shocked at how amazingly flimsy this thing really is. The bottom wood actually came with a huge crack; big enough to leak out all the sand. The feet were glued on with cheap glue and 3 of the 4 came off in transit. Based on the construction, I'm amazed it was even in one piece.The reason this gets 2 stars is that the accessories are pretty decent. And the sand looks fine. If this wasn't cracked in the center, I'd most likely have kept it and it would have "worked" for its purpose. Having said that, if you are looking for a desktop zen garden, look elsewhere.
[A]: Negative


[Q]: An extremely helpful gem on a complex subject of second century religious authority and textual use. For anyone serious about this period and the interelation of cultures, this book is essential. Is it complex and detailed? Of course, it must be to argue the point. Should you buy it? Yes, unless you want to keep running back to the library. I write this only after thoroughly disagreeing with the review above.
[A]:
Positive
