[Q]: Easy to use and makes excellent coffee. Very easy to clean. I am not very fond of the permanent filter design, but otherwise it is fine. This machine brews coffee exactly in the amount of time you select which saves a lot of time. Update: The plastic gear that is on top (pour spout) broke off. But this thing still works. Not sure if they make them with metal gears. Just want others to be aware of that. We may buy another one.
[A]: Good Review


[Q]: I haven't done any serious studying for my exam. This will be the first time I've ever sat at a exam after watching a TV show and looking all over this book before I go into each section, trying to find anything. I can almost get through it...
[A]: Bad review


[Q]: What the title does not really tell you is it's ALL about Mark Twain and nothing else. It's mostly just short bits from books he wrote. I feel this book is being marketed at people who think "Mark Twain" will teach them something. Not so much.
