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: Stupid me - didn't read the label before buying. I thought this would be pure xylitol, but later noticed they've added Dextrose with Maltodextrin and sucralose (Splenda) for extra sweetness. I don't know what proportion of this product is xylitol.
