Example Input: I chose this rating because it does not have good suction power. It is easy to clean and handle. It's very light. My previous vacuum was the Hoover WindTunnel Animal Bagged Upright Vacuum, UH70210, which had better suction. Now I won't recommend it. This one isn't as powerful but you can't beat the price for getting a pet hair cleaner. The dust chamber seems to expand everytime i use it, so i'm looking for an accessory container that will make cleaning easier.
Example Output: Good Review

Example Input: This book was a complete waste of time and money. It does not teach anything. Just lists the different ways to cook each dish. If you want a great cookbook, get Rachael Ray's- she is hilarious. My only advice would be if you are going off the grid this will give you some inspiration, but for everyday cooking it's useless. A lot of recipes have more than 1 ingredient listed. Which I found odd. I've never used most of those ingredients in one recipe. Do not buy.
Example Output: Bad review

Example Input: Not the best but definitely not bad. The concept was good and it had moments where I wanted to know how they would get out of all this mess. It did take me one day to finish so for that, I'm thankful. No cliffhanger endings. Would have been nice to find some new twist or something that caught our attention. Maybe just one more bad guy in it. Also, it's kind of short - only about 100 pages. It's probably a pretty good idea for an adult book.
