Ex Input:
I had been planning a trip to the Galapagos Islands, and this guide was required reading by the tour group guide. The guide is thorough, providing information of interest and useful for all travelers traveling among islands, but the format of this book severely detracts from any pleasure of seeing them. There's an interactive CD-ROM provided which allows you to see photos that were previously in the book, but not the whole trip. Additionally, there are many grammatical or spelling errors.

Ex Output:
Bad review

I love the quality of this item. Pros:It locks securely. It is adjustable to take your glasses and not get in trouble for them being too big or small. The arms are super strong -- I can put on my eyeglasses, sit down, watch television, then lean back against the arms. Cons: Mine came without a manual. There was no paper contact with where it goes together. And no instruction sheet.

Ex Output:
Good Review

I bought this because all my other chargers broke and thought it looked cool and would be easy to use on long trips. Well, the first time i used it, when i plugged in a device, It fried the socket in my truck. And now, it's completely toasted. This product is not worthy of being sold. Do yourself a favor and don't buy it. Buy the real charger from apple. Spend $30-40 dollars with Apple directly so you have that confidence you'll never need a charger.
