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. 

Example Input: I don't like using artificial sweeteners because of the chemicals and because they don't taste good. I am a caregiver for my diabetic dad, and once I discovered this product I was hooked, except that it is hard to find where I live. When I found it at Amazon I put it on auto ship so I don't run out.  The price has gone up a lot since I first found it on Amazon, however, it still costs more in stores if and when I can find it there. I make limeade with this which I keep on hand at all times. In a gallon container of water I add 1 cup of lime juice and 2tbsp. of stevia powder. It is refreshing and almost no calories and no chemical aftertaste.  My dad uses the stevia in his coffee and his oatmeal. I haven't tried cooking with it although I know they make one designed for baking, which I'll possibly try this winter.
Example Output: 5

Example Input: I have managed to find these crackers in other countries on our travels but had run out. I love that they are individually wrapped small packets in a stay fresh container. This makes them great to carry in my purse, take to work or on airplanes for snacks etc. Also love that they are not overly salted like so many American brand crackers. Company that shipped them did a great job - fast too!
Example Output: 5

Example Input: This peppermint stick is delicious and fun to eat.  My dad got me one for Christmas because he remembered me having a similar one when I was a little girl.  I'm 30 now and I love it!
