Instructions: In this task, you're given a review from Amazon's food products. Your task is to generate a rating for the product on a scale of 1-5 based on the review. The rating means 1: extremely poor, 2: poor, 3: neutral or mixed, 4: good, 5: extremely good.
Input: This is an excellent product for the non-gluten diet. They're good alone as a snack, or you can make a light meal with them by using these rice crackers as a base for spreads or little crispy sandwiches. Excellent substitute for crackers containing gluten. Only criticism - wish the price would come down.
