I purchased this MP3 player as a Christmas gift for our daughter only to find out on Christmas Day that is not compatible without our computer despite every update available. While we could see the preloaded video and it is very clear and bright, we were never able to upload any music. My husband (who is computer wizard) spent 12 hours trying to get this thing to work, but without any success. Next time we'll buy an IPod.

Ex Output:
Negative

Even that single star is more than this book is worth. My Engligh professor assigned this book to me during my sophomore year of college (along with Nectar in a Sieve, a far better, though not terrific book), and what little I remember of it was that it was just awful (and offal). Her writing is repetitive and choppy, perhaps descriptive but disgustingly so. Do we really need to know the "wetness between [her] legs", or that she cooked her menstrual fluid into some poor soul's dinner? I couldn't stand the book. If you want quality, read something by Neil Gaiman, or Stephen King (his descriptions of a girl coming of age in Carrie are much better than this book). Drop the book, throw it, burn it, whatever. It's just not worth reading. How many trees did we lose to its production (and, more importantly, how many talented young writers were rejected because this woman was published). It's just a book not worth reading about a story not worth telling.

Ex Output:
Negative


Ex Input:
Good quality and fairly easy to assemble, although it helps to have 2 people. It is quite comfortable and looks nice.

Positive
