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: This small vacuum cleaner is really powerful enough to clean the dirt / food particles in car. Cleans well even in the small gaps between seats. The long pipe accessory makes it easy to clean below seats. This works well even without the car engine off in my crossover. And the long cable helps clean inside as well as outside the car. The filter is easy to remove and clean. A must have item.
Example Output: positive

Example Input: One star for cuteness and color variety. The rest needs reworking. The touch sensitivity is annoying as it changes colors & modes every time you touch it, which leads to the biggest issue with this nightlight. You HAVE TO PICK IT UP to reach the hard to get to, tiny power button in the rear next to the charging port. For some inexplicable reason, the remote does NOT turn the unit on unless you first press the power button (again, tiny and hard to access in the rear). Poorly designed. So basically to turn it on, you pick it up, press the power button, and since you’re still touching it as you put it down, it cycles through modes. Did I mention it deflates/collapses easily, so you have to reshape it first before putting it down. By the time you set it down it usually ends up on the fast color cycle which is super annoying. Just make the remote able to turn it on so you don’t have to manhandle it every time. Also, the charging port itself isn’t a great fit for the charging cord. Really feels like you’re brute forcing it in. And a full charge is surprisingly short so it’s pretty much plugged in most of the time. This product obviously didn’t go through any honest testing. Definitely disappointing and would not recommend.
Example Output: negative

Example Input: This silicone swimming cap is so nice. The swimming cap can be taken off quickly and easily without snagging hair and be stretched to more than double its original size. Can be stretched to more than double its original size.
Example Output:
positive
