Input: Consider 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.

Output: Bad review


Input: Consider Input: Great for my puppy. I have a puppy and wanted to purchase her something so this would protect her from scratching as well as prevent further chewing. The fabric seems durable. She still gets it with the treats but doesn't chew on everything. It has held up nicely.

Output: Good Review


Input: Consider Input: I bought this for a small dog (about 12 lbs) to keep him occupied while I'm at work. When he started using it, the collar felt tight and wasn't allowing him full freedom of movement, but now we have been wearing it regularly since getting it two weeks ago. He has calmed down so much that he actually lies down. We just got one size up from recommended sizing on our other dog (12 pounds). If nothing else, I will buy again.


Output: Good Review
