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 love this ring! Got the silver one as a replacement for my old claddagh ring, and I love this. Personally, I found the sizing to run a bit big compared to what is advertised on the sizing, but I had no problems with getting a prompt return, and reordered the correct size. I love the finish on the ring, the weaving detail is regular throughout and well done. Very comfortable, and not too wide of a band.
Example Output: 5

Example Input: Looks just like the picture. Fits nice and is well made. Only reason for lower rating is being the product absolutely reeks. I've laid it out in my home and I'm hoping that the smell goes away by my party on Saturday.
Example Output: 3

Example Input: Unfortunately I had to return the pack. Our dog was right between two sizes and it didn't fit her well enough. That being said, I was impressed by the material and how easy it was to adjust and put on the dog. Would have enjoyed using it if she wasn't between sizes.
Example Output:
