Example Input: The only complaint it really has is that there was a defect on one of the shelves. I would purchase again for small spaces. Well made,as expected from Ikea. A great buy. Very solid construction.
Example Output: Good Review

Example Input: The story started out well for an erotic novel and got more interesting until the end. It just became a book of sex then love story. So I am in no hurry to read any more. Sorry!
Example Output: Good Review

Example Input: After two weeks of use the sensor doesn't send signal any more. I'm not able to return this item because I didn't open yet. I can't even ask my friend what should I do so that he can give me an alternative gift. Very disappointed with this purchase. Maybe I'll see something better in future purchases.
Example Output:
Bad review
