Input: Consider Input: This was a bad buy. It did not work properly and I am very disappointed with it. Not good customer service. After hours of troubleshooting we realized the unit needs to be returned for replacement. Hopefully it will end up working properly.

Output: Bad review

Input: Consider Input: This a disappointing book.. No real plot at all. Slow and boring. Was this suppose to be some new twist on a true story? I have read every single novel Mr. Brown has written, however after reading this, it is definitely my last.

Output: Bad review

Input: Consider Input: I like this product. It's a great idea, but it was so complicated to use - very time consuming for the amount of work that actually needs done. In my opinion I'm not worth taking apart and redoing my toilet seat all over again unless it's something really important, which if that's what you want, save your money. This didn't meet my needs. It also doesn't clean as well as other methods I've used (like vinegar in a spray bottle - same result with more elbow grease).
Output: Bad review
