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: I had some trouble from the start with these cartridges. First, when printed, they show two inks instead of one, which makes printing not very accurate. Second, if you have ink level to about 1/3, my printer will tell me that one is low and won't send a new print job unless all cartridges are replaced. It doesn't bother me, but it also seems like HP screwed up the system where this happens.
Example Output: Good Review

Example Input: This book was not what I expected - maybe it's just me?I'm looking to learn German for about a year. The grammar of this book left me thinking "what???" and that made it difficult to learn. I would have liked some more explanation for how the sentence were formed.
Example Output:
Bad review
