input:  Now, answer this question: Title: A Big Disappointment Review: After having read Kaffir Boy, Mark Mathabane's eye-opening account of township life under apartheid, I was looking forward to his insights into US race relations (as the dust jacket promises). Unfortunately, this book contains virtually none. It is a big bore, so full of self-congratulation for having beat the odds, for being so open minded, for being so well-read, for being such a wonderful writer, etc. that by page fifty my interest was replaced by irritation. The relentlessly stilted nature of his prose does not help (he crams in so many SAT-words, it's as though he were trying to fulfil a quota). Finally, he seems to think the Acknowledgements section too confining, so he peppers his mundane descriptions of moving from this city to that with mentions of every nice person he ever met in the past ten years. Thumbs down. Is this product review negative?

Arfken's Mathematical Methods for Physicists book has a section that is better than this book. The problem is that it is not extensive. Is this product review negative?

input:  Now, answer this question: Title: poor design Review: I actually purchased two of these because it has one of the highest amp capacitiesof the adapters I looked at. Unfortunately this means little if the plug comesapart. On my wifes first use she attempted to unplug a device and the plug came apart.Similar to others comments. At the very least the mfg should have glued or bondedthe two halves together. I take others reviews with a grain of salt, but shouldhave listened to others, this plug is junk.
