Example 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.
Example Output: Good Review

Example Input: Nice book, the only thing I didn't like about it was that each time a new topic came up throughout the first 30 pages or so we learned more than needed and it wasn't very interesting. It also gets a little boring around page 100 but does pick up. If you think you're going to take pictures of every bird in a local neighborhood, buy several books on your own first, this book is an okay one for that.
Example Output: Good Review

Example Input: I ordered this book for a class and was not very pleased that my favorite poem was, by far the least, in it. The poems were great but there is only so many of them. For students who want the poetry as well buy this, because that's what they need. If you need everything don't order!
Example Output:
Bad review
