Quite a heavy weight text but written carefully and clearly - plenty of examples and a very professional CD loaded with useful data and programs.

Q: Title: Confusing, but bearable. Review: I rated but a two star because I thought the book was confusing, and it didn't exactly have a main subject. It had detail(earning one star) and juicy words(earning the other star)though.It was also hard to understand. Does this product review convey a negative or positive sentiment?

Q: Title: "Barbie Man" Review: Our girls love Prince Stefan. As parents we have gotten lots of giggles about how "girlie" this prince is. What happened to the "Rugged Ken / GI Joe" type? Anyway, product is of good quality. The hair had some weird glue like substance on it at first but thankfully it has worn away with play.

Q: Title: Etymotic ER-6i Review: I just loved the Etymotic ER-6i - while it worked. However my first ordered earphone left side's volume reduced about 90% less after about 2 weeks usage. Though I tried to clean and change the filter, it did not help. Because I really loved the sound quality and noise reduction level (i am a gardener and I am using very noisy machines) I ordered at once another pair of earphones. Unfortunately the second one took only 1 day. In the second day morning I realized, the left ear bud just quitting to work like the first one, only the sound level went down "only" about 60%-70%.After that I suspect this is a common problem with the ER-6i (Possibly that is the reason to sell for less on Amazon)I sent an e-mail to Etymotic and waiting for answer about exchange the defective items. I hope they know about the problem and solved it already. Does this product review convey a negative or positive sentiment?
