Question: Title: Hours and hours of pain... Review: This book was designed to be used in conjunction with the intensive introductory hysics courses at MIT and Caltech. At these schools, the kit with all the parts for the lab is supplied by the instructor. Of course, if you are anyone except a student at MIT or Caltech, thi list is unavailable to you and the book will be quite confusing... not that it is any less confusing if you have the parts. While there is a lot to be learned in this small text, there has got to be a less painful way. This one book alone has caused more sleep loss among freshman than anything else I can think of.

Question: Title: what happened?????????? Review: I've been buying ZICO with mango in 11.2 oz. tetra-paks almost since they started offering them here on Amazon. However, just as another reviewer explained, the most recent batch I received was horrible, it went from being the best coconut water to the worst I've ever had. The packaging was slightly different and most alarming, the individual box no longer says anything about being from Brazil. If this continues I will never buy this product again. If you are having the same experience, please speak up on here so maybe we can get this fixed...... Does this product review convey a negative or positive sentiment?
