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 write reviews at all but I'm just going to say that this is a very decent product to buy if you're not looking to spend hundreds of dollars on a mixer, phantom power supply, and pre-amp for XLR mic recording. Because guess what this little thing has it all in one all for a low price! Cop you one!
Example Output: 5

Example Input: We received a gift box that contained the Stonewall Farms Pancake Mix and they were out of this world. They are the lightest, fluffy and flavorful pancakes and waffles you will ever taste.  And the price on Amazon is a big savings over ordering from Stonewall Farms.  Don't shy away from the larger size and the two pack because you will devour these pancakes in no time.
Example Output: 5
