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.

Ex 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.

Ex Output:
3

Ex Input:
These were easy to install and seem to be of decent quality. The finish looks good with all my different door styles and colors. I really wanted all my doors to be keyed alike, and this set provided that option. In fact, each set came with four keys, so I have plenty of spares.

Ex Output:
4

Ex Input:
I really do like their other products, their face cream, and their body creams are great, which is why I thought I would try their face cleanser but it is just terrible. It is thin and very watery, it leaves my face dry and tight feeling and worst of all is the smell. It smells like the stuff they use to clean rest stop bathrooms, I'm just going to throw it away. I really didn't want to give it any stars at all.
