Example Input: When used in conjunction with a new water filter i no longer have to replace my Brita when we change filters. Very easy and fast to get the water flowing. You can switch them out more then once.
Example Output: Good Review

Example Input: My wife was really excited when I gave her this coffee maker. She loves coffee, but it is sometimes hard to make a great cup of coffee. First, the pot has NO carafe. This should be obvious and I'm guessing most people realize this. We have had numerous other Cuisinart thermal machines in our office for many years, and all were fine. The filter basket on these new ones does not seem as strong or durable, so we will probably just use paper filters.
Example Output: Bad review

Example Input: I am not sure why this case is rated so highly when it does not fit at all. It was very snug on my Macbook Pro Retina. The bottom part stuck up a bit. There were no issues for the top part. But the back of mine would slide forward and fall off. Maybe if you have one that fits without problem there wont be any problems. Just not mine. :( If you're looking for an actual case, don't buy this product, but do get another one.
Example Output:
