Example Input: This product works great with my Sony NEX 5.I was a bit disappointed when the first adapter that was sent to me didn't fit at all. You are supposed to insert batteries through little holes, and as soon as it snaps in place, you're suppose to twist or pull back so the battery will make contact. The holes looked too small for me, but if you force them in with enough force, they snap into place. But now that I've got this one right, it's pretty sturdy.
Example Output: Good Review

Example Input: My cats won't touch the stuff. They know better than me. Oh well, back to their nasty little pellets, which they gobble down. Thanks for nothing. :-(
Example Output: Bad review

Example Input: I enjoyed the first book in this series, so figured I'd read them all. I bought it for Kindle and downloaded most of it. I've just recently started a new project, &#34;Making Books.&#34; The first four were on my shelf. Just got through #4 today. These books are getting shorter (really short books), shorter, shorter. It's too bad how things have been dumbed down from what they used to be.
Example Output:
