In this task, You are given a review of Amazon's food products. Your task is to divide them into two classes: negative or positive, depending on the content of the review.

Example Input: Keep your money! I bought this so I could check my husbands BP. I took it out of the package, set it up, and took his BP. The sphygmomanometer broke in the first use. I didn’t even get to finish taking his BP. It felt really cheap too. I also didn’t like that I couldn’t hook the sphygmomanometer to the cuff. It is part of the pump.
Example Output: negative

Example Input: I am writing this review after 7 months of use and I must say that this strap is the best I've ever used. It is holding up extremely well. Still looks as good as new. Leather is high grade and Quality is second to none. People compliment it all the time as it looks so good on my Fuji X100F. Just looks at the quality of the mounting rings used on this thing compared to my old strap. It is so my thicker and feels way more secure than others. I also like the fact that the mounting ring is also protected from scratching the camera. If you are looking for a quality strap that I believe will last you a life time then look no further. Save yourself multiple purchases looking for the right one and just get this one. You will not regret it.
Example Output: positive
