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. 

Delivered by UPS, this product is just about perfect.  It does not have a disagreeable smell and the dogs love it.  It is much less expensive than prescription dogfood and our dogs are thriving on it.  You can even see an occasional pea and/or carrot. No grain to worry about.

It's that good!  Heaven if you like cinnamon.  Tastes sweet with no sugar.

This was a big disappointment. There was no raspberry or pomegranate flavor to this. The color is green and not very appealing to look at. However it does work as a great antioxidant.
