Example Input: Easy to use and makes excellent coffee. Very easy to clean. I am not very fond of the permanent filter design, but otherwise it is fine. This machine brews coffee exactly in the amount of time you select which saves a lot of time. Update: The plastic gear that is on top (pour spout) broke off. But this thing still works. Not sure if they make them with metal gears. Just want others to be aware of that. We may buy another one.
Example Output: Good Review

Example Input: Very easy to use. Only problem is you must remove the battery every time which takes some time. A few pics have already been taken and it keeps on taking. We went kayaking last weekend - took about 20 pictures before turning off camera. Great little camera. I would love an underwater case for it.
Example Output: Good Review

Example Input: I received this book as a gift. It is a cute idea for kids, but don't buy it to play with if you're wanting something that isn't going to break. We got 2 of them and only one was usable by my son. The other broke almost immediately. My son did love the idea, but can't use both. I'd rather have just found some plain old magnetic tiles. He liked playing with those, so we'll be trying those next. Too bad because I do like it.
Example Output:
Bad review
