In this task, you're given a review from Amazon. 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, 4: good, 5: extremely good.

Example Input: I like the pages and the layout. The problem is if you have to carry it around much the outside cover deteriorates quickly. After just a week or so mine is coming off.
Example Output: 2

Example Input: All of the leggings I have ever purchased have always been one size fits all/most, but these are the first ones that I've ever had trouble with. The ones I received were not very stretchy, especially in the waistband. They also had a very strong smell that lingered after the first wash. I guess they are fine for the price, but I would not buy them again.
Example Output: 3

Example Input: My friend said this was the best eye glass cleaner. I loved that it has it's own case and is light to carry. But I don't see that it cleans my glasses so well. I bought one for my husband and he felt the same way. Too bad, good idea.
Example Output:
