Example Input: I just ordered and received my new Dell laptop with Windows 8. With all the negative reviews it looks to be a fairly simple install using this software. However, for some reason, Amazon won't ship me the Microsoft Office 2010 program until after I'm finished installing Win8 - you can't cancel within 30 days. It also says that because of shipping it will take up 1 hour longer than expected for delivery. If they send me, as promised, Word 2010, then it's going back to Amazon, not me.
Example Output: Bad review

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: I am returning this book, because the title is misleading and in fact it is not by Tom Waits but his former group Dead City Ramblers. Although this book would probably rate a high for people who do NOT know about Dead City, it does provide some nice pictures of Tom's life as an adult. For those who are interested in knowing more in-depth info on what happened to him, like you wouldn't find anywhere else, then get another book. This one just doesn't even come close.
Example Output:
Bad review
