input:  Now, answer this question: Title: Very overrated Lincoln biography!!! Review: I generally enjoy reading biographies, but this one was an exception! A very boring read! I did not think that Lincoln was being portrayed as overly religous as another reviewer did, but I seriously doubt that lincoln had evangelical inclinations. I was dissapointed in the lack of overall perspective of Lincoln's life. I feel that there was too much concentration on Lincoln the politician (his political development) and not enough about his family and social life. I wanted to know Lincoln better on a personal level and I did not feel that this book provided much insight. I may have been expecting too much, but I prefer a biographry that maintains my interest rather than puting me to sleep, as this one frequently did. Is this product review negative?

input:  Now, answer this question: Title: Do not buy this B60 Brewer by Kuerig Review: I am very disatisfied with this product. Bought it in May 2011 and it is now not brewing coffee like it did the first couple of months of use. The water is not coming out of the machine. I have only been using filtered water and have descaled it three times since May. Called their Customer Support people and the lady had me use a paper clip to clean out the pin in the K-cup tray and the pin in the head of the machine. This works for a additional cup but then it stops passing water again. After reading all the other reviews it seems that this is a recurring problem. With all of the bad reviews that I have read it seems that this might be something that is ready for a CLASS ACTION SUIT. It seems like alot of us have been taken for alot of $$$$$$$.
