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 really wanted to like this product. I hate having to wash my hands free bras all the time, so I thought this product would cut that part out of my routine. I always find myself using this only when I don't have a hands free bra available because they're dirty. It takes way too much time to put on and set up the pump to the right spot to get a good flow going.
Example Output: 3

Example Input: Bought the product in January, worked great until March and then started to give inaccurate readings for the outside temperature...off by approximately ten degrees...very disappointing !!!
Example Output: 1

Example Input: I had hoped the colored sleeves would work like a locking bit holder or the button on the back of a ratchet to lock the sockets in place. Not so; the ball in the side of the square drive is properly spring-loaded, but the sockets just pull off as with any less expensive socket adaptors. More important is that they do not properly fit and lock into my impact drivers. I must, therefore, hold the adapter in place for use.
Example Output:
3
