Example Input: I love how this product makes me look in my clothes!!! its shapes me into a perfect hourglass! i dont know if the claim that it permanantley reduces your waist after 30 days is true because i havent had it that long. my only complaints are that it is a little too short, so i still have a small bulge over the top in vthe back and i think it may be stretching out as i wear it as oppossed to it shrinking me, but overall, it is the best shapewear i have ever purchased. i love it and would recommend it to anyone.
Example Output: Positive

Example Input: The subject is trivial and boring. The writing skill mediocre.I was stuck in Sri Lanka and downloaded it by mistake when learning how to use my new kindle. Decided to take a look.Sorry, perhaps just not my type of book. It is no literature.
Example Output: Negative

Example Input: We have owed these plates in white for quite some years. maybe six or more. I just replaced all of them with a set from Crate and Barrell. They are heavy and seemingly well made but they have been faulty in a a number of ways. First my biggest complaint is on the white plates everytime you happen to scrape them with silverware it leaves a permanent mark. Never wash anything stainless near them in the diawasher since it will mark it up there as well if it rubs up against them. After years of use they looked horrible with marks all over them. They also seemed to chip very easily. So between the chips and marks all over them I couldn't take looking at them anymore. They also are not good in the microwave. They get very hot and the food not so much. I would not recommend for everyday use. Maybe the dark colors would show less marks but if they chip it will be very noticable. My advice is to purchase bone china or porcelain. I will never buy these again.
Example Output:
