Input: Consider Input: It is definitely a unique design. Unfortunately, it does not function well. You have to be very precise with your touch and you don't really feel the brush on my teeth at all. Not sure how else I can complain about something when it's still working perfectly after several months. One of the things that makes this toothbrush stand out is that there is no battery. With other batteries, they inevitably fail or die because they're always sitting around. This one doesn't.

Output: Bad review

Input: Consider Input: Nice book, the only thing I didn't like about it was that each time a new topic came up throughout the first 30 pages or so we learned more than needed and it wasn't very interesting. It also gets a little boring around page 100 but does pick up. If you think you're going to take pictures of every bird in a local neighborhood, buy several books on your own first, this book is an okay one for that.

Output: Good Review

Input: Consider Input: I ordered these for work because they are the perfect size and color to match my brown office chairs. They arrived today, opened one bag of them up only to find that there was no fabric or padding in this package whatsoever!!!! What a rip-off! My husband is going to have all his Christmas stuff shipped back! I'm so disappointed and frustrated! Hopefully I'll just eat this loss and won't order anything more from amazon. :(
Output: Bad review
