Question: My husband and I didn't have time to attend an 8 hour birthing class at the hospital, so we opted for this video. It was very informative and helped us understand what was happening when we went to the hospital. It was a little cheesy, but definitely worth getting.

Answer: Positive


Question: I did not really care for this book. I found the plot messy and muddled, with many clumsy devices and scenes that felt forced (the climax, in particular, seemed very rushed, cinematically speaking). The characters, for the most part, were thin - and perhaps the author reached too far in casting the reference-net. I wanted to like it (I very much enjoyed Alan Moore's tales of the Extraordinary Gentlemen's League)... A very intriguing idea though (I give the acorn a golden prize but the oak grew sickly)... Maybe it is your thing; it was not mine.

Answer: Negative


Question: this made me really dizzy so I had to stop using it after only one use. I ended up tossing it out.
