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: Good product for the price. I like the fact it has the recommended dosages of each ingredient to be effective. All of our horses are on this and are doing well. The other nice thing is that our horses actually like to eat the product. I've got 2 that could pick the peas out of a tuna casserole (if they were allowed to eat tuna casserole) and they seem to like this supplement. If you have picky horses you know how frustrating it can be to buy supplements only to have them turn their nose up no matter how much grain you try to hide it in. Give this a whirl, it seems to have a sweet taste to it and it is effective.
Example Output: positive

Example Input: Unlike other reviews I read before buying , my locks came sealed and with matching codes , nothing really special about the locks besides being reliable and sturdy locks good for use at a gym .
Example Output: positive

Example Input: I have bad dental pain. I got it originally for my husbands nerve pain in his elbow. It really did not help his elbow, but I put it on my gums like orajel and it was an instant pain reliever. It lasts for hours.
Example Output:
positive
